Answer explanation

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It is a mnemonic acronym used to remember the order of operations when solving a mathematical expression. The order of operations is important because it ensures that the expression is evaluated in the correct order. Parentheses are evaluated first, followed by exponents, then multiplication and division, and finally addition and subtraction.
