How is 10-10x10+10 = -80? Answer or Solution Explained Step-By-Step!

We shall solve the question 10-10x10+10 = -80 using PEMDAS and BODMAS below.

A. Solution to 10-10x10+10 = -80  Using the PEMDAS Method

  • PEMDAS says you would do parentheses, exponents, multiplication/division, and addition/subtraction.
  • There are no parentheses or exponents in the problem, but there is multiplication. Thus, you would do 10*10 first, so it would be 10–100+10.
  • Now that everything is just addition/subtraction, you would do the problem from left to right.
  • 10–100+10 = -90+10
  • -90+10= -80.

B. Solution to 10-10x10+10 = -80  Using the BODMAS Method

  • According to the BODMAS rule, multiplication has to be performed first.
  • So, the equation becomes 10–100+10.
  • Next comes the addition of the numbers: 20–100
  • And the last step will be subtraction: -80
  • So, -80 is the correct answer.
