Well, just give a read to this stuff to know how to solve math problems with this calculator for math, basic operations in mathematics, and much more! But, first, let’s begin with the basic term of mathematics.

About Mathematics:

Mathematics explains various topics such as quantity, details, and symmetry of the structure, characteristics of space, and process of change. It uses and searches for some new patterns to express new estimations. Furthermore, it resolves the mysterious equations with the support of mathematical proof. Math calculator assists human beings in all these quires.

Also, calculator-online provided smart & free math calculators online for students and teachers to perform mathematical exploration and experimentation calculations.

What is Mathematics in Our Daily Lives?

It plays a very significant role in our daily lives to make a precise order and to prevent chaos. Certain abilities that are supported by mathematics are power of valid and logical reasoning, art of creativity, abstract thinking patterns, ability to think critically, skills to solve a problem and effective skills of communication. All these characteristics provide a way to solve math problems effectively. Also, you can try this scientific notation calculator to add, subtract, multiply, and divide numbers in scientific notation.


How to Solve Math Problems?

Math problems can be solved by:

  • Logical solutions
  • The mathematical equation that has a firm background
  • Abstract formulas that have logical reasoning as well
  • Different formulas and many more to give mathematical answers.

Basic Operations In Mathematics:

There are many basic operations in mathematic that provide basics to solve all the mathematical problems. Some of them are discussed below. Even math calculators use all these basic operations to solve simple as well as critical math problems.

Addition (+):

In mathematics, the process of addition is normally represented by the symbol of plus “+”. It is one of the basic operations in arithmetic. The process of the addition of two numbers will result in the over-all value or sum of those two original values combined. Some of the elementary instructions are listed below:

  • If you have two positive values, then: positive + positive = positive answer after addition. For example, 3 + 3 = 6.
  • If you have given two negative values, then you have to add them first but the answer will be written with a negative sign. For example, if there is –5+ (-8) = –13. Other than the manual calculation a basic math calculator online free can be a great help for this purpose.
  • If you have two values one with the negative sign and the other with the positive sign, then you cannot add them up. You have to subtract them. For example, if 5 + (–20) = –15. The sign that is present with the greater number will be written with the answer. Any advanced math calculator can perform this function automatically.


  • 3 + 2 = 5
  • 1 + 1 + 1 + 1 = 4

Subtraction (-):

  • It is the operation in which we take two different numbers to measure their difference. the symbol to represent this operation is named the minus sign and represented by “- “.
  • If you have two numbers with different signs and you want to subtract them then forget the signs for a while. Now subtract the smaller values from the larger one. Now put the sign of greater number with the answer. It is the basic math problem-solving strategy.


  • 3 – 2 = 1
  • -3 +2 = -1
  • -3 -4 = -7

Multiplication (x):

In mathematics, while solving math problem, the operation of multiplication represents the addition ofequal groups. When you multiply, the total number of anything will increases. For example, 3×4 =12. In this example 3 and 4 are known as factors while 12 is known as the product. However, for the answer verifications, an online math calculator might be a great support.

  • Any number that will be multiplied by 0 will give result 0.
  • Any number that will be multiplied by 1 will give the same number as a result.
  • If you multiply any number two, then the original number will become double.


  • 2 * 3 = 6
  • 3 * 3 = 9

Division (÷):

Division is basically a process of splitting any value into equal parts or groups while solving math problems. We can say that It is the outcome of “fair sharing”. For example, if there are 10 chocolates, and 2 siblings want to divide them equally then according to division each will get 5 chocolates. 10 divided by 2 = 5.

  • If you want to divide 0 by any other number, then the answer will be 0.
  • If you divide any number by 1, then the answer will remain same as the original number.

Percentage (%):

In mathematics, the operation of percentage is a number that use too represents a fraction of 100. It is represented by the symbol “%” or simply as “percent” or “pct.” For instance, 5%. Also, you can try our math help calculator to solve the percentages math problems instantly and accurately.

  • It has a certain formula in manual calculations that is:P X V1 = V2


  • In mathematics, the term fraction represents a number that is a part of a whole.
  • It basically consists on a numerator and a denominator.
  • In the fraction the numerator represents the amount of equivalent parts of a whole.
  • In the fraction the denominator is the entire number of parts that make up said whole.

What is Square root?

Square root of any number x is another number y such that y. ² = x.

  • For example, if you have a 4 and another number −4 then they have square roots of 16, because 4² = ² = 16. This function can easily be operated via scientific calculators.

How to Make An Estimation About Root?

In mathematics, the general root can also be represented as the nth root.

Estimating a Root:

To calculate √a you have to follow some simple steps below:

  1. First of all, you have to Estimate a number b
  2. Now Divide number a by number b. If the resulted number c give back a desired decimal place, then you can stop here.
  3. Now you can use Average b and c and as a new guess

How to Find Area of a Triangle?

There are numerous dissimilar equations for computing the total area of a triangle, dependent on what data is identified.

  • The most frequently acknowledged equation for computing the total area of a triangle includes its base, b, and height, represented by h.
  • The “base” of the triangle represents any side of the triangle whereas its height is signified by the length of the line section that is drawn from the vertex just opposite to its base, to a point on the base which forms a perpendicular.
  • If the length of two sides and the angle among them, then a formula can be used to signify the total and actual area of the triangle.
  • Now if a = 9, b = 7, and C = 30° then area will be equals to = ½ multiplied by sin (C) then on putting the values we will get 15.75.
  • You can also use the above calculator to calculate the area of a triangle by following the formula.

Is a TI 84 a scientific calculator?

The Ti84 Plus is a graphing calculator made by Texas Instruments that is also a scientific calculator with functions includes sin, log and taking the square root of any number.

What mode should my calculator be in trigonometry?

It is crucial to have the calculator in the right mode as that mode setting indicates the calculator which units to assume for angles when evaluating any of the trigonometric functions. For instance, if the calculator is in degree mode, it evaluating sine of 90 results in 1.
