Solve the Expression: 6·(3+5·2-13) Using Order of Operations

Mathematical expressions have a specific order that must be followed! Just like reading instructions for a recipe, doing steps out of order gives you the wrong result. Always use PEMDAS order.

Inside parentheses, you still follow order of operations! So in $3+5\cdot2-13$, do the multiplication first: $5\cdot2 = 10$, then work left to right with addition and subtraction.

Use the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Some people remember it as "Please Excuse My Dear Aunt Sally."

Any number multiplied by zero always equals zero! This is a fundamental math rule. So $6 \cdot 0 = 0$, $1000 \cdot 0 = 0$, even $-25 \cdot 0 = 0$.

Work through the problem step-by-step again, or use a calculator to verify each step. For this problem: $3 + 10 - 13 = 0$, then $6 \cdot 0 = 0$ ✓
