What Exactly Is PEMDAS?

PEMDAS is an abbreviation of Parenthesis, exponents, multiplication, division, addition, and subtraction. PEMDAS is a sequence used to solve mathematical equations.

Sequence Used by PEMDAS:

  • The sequence moves from left to right
  • Parentheses must be solved first
  • Solve the exponents just after solving the parentheses
  • Then perform multiplication and division operations present in an expression
  • After solving the Multiplication/Division operations, solve the Addition/Subtraction functions

Rules for Adding, Subtracting, Multiplying, and Dividing Two Numbers:

Here are some rules that are followed generally and also followed strictly by our order of operation calculator:

For Adding Two Numbers:

  • If the signs of both numbers are the same, add both of the numbers and place the same sign with the output
  • If the signs are different, subtract the shorter number from the other and place the sign of the larger number with the output

For Subtracting Two Numbers:

  • Change the signs of the expression according to the sign of the first number

For Multiplying Two Numbers:

  • If the signs of two numbers are different, place the negative sign with the output value
  • If the signs of two numbers are the same, then put the positive sign with the output value

For Dividing Two Numbers:

  • When you divide a positive number by a positive one and a negative number by a negative one, the output sign will be positive
  • But when you divide two numbers having different signs, the output sign will be negative

Our order of operations calculator also considers the above-mentioned rules to apply arithmetic operations to mathematical expressions.

Practical Example:

Let us resolve an example below to clarify your concept!

Example # 01:

Solve the expression using PEMDAS:

50 + 10 x 0 + 7 + 2


First, we will solve the multiplication

= 50+10*0+7+2

= 50+0+7+2

= 50+7+2

Then add all the remaining terms

= 57+2

= 59
