What is the order of operation in a math problem?

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is the hardest operation order?

Four hard order of operations problems

  • Problem #1:
  • 6 ÷2(1 + 2) This problem was on Facebook and many people got it wrong. According to PEMDAS, The first thing to do is parenthesis. 6 ÷2(1 + 2) = 6 ÷2(3) Now this is where many people got it wrong.
  • Problem #2:
  • Problem #3:
  • Problem #4:
  • -10 ÷ (20 ÷ 2² × 5 ÷ 5) × 8 – 2.

When to use Order of operations?

Order of operations. In mathematics and computer programming, the order of operations is a rule used to clarify which procedures should be performed first in a given mathematical expression. For example, in mathematics and most computer languages multiplication is done before addition; in the expression 2 + 3 × 4, the answer is 14.
