What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is the error in the calculation 5 - 3 + 2 = 0?

Back

The error is that addition was done first instead of subtraction. The correct order is to subtract first: 5 - 3 = 2, then add 2, resulting in 4.
