Solve the Expression: 9:(3×2) Using Order of Operations

The colon (:) is another way to write division, just like ÷. So $9:(3\times2)$ means 9 divided by (3×2).

Because of parentheses rules! Whatever is inside parentheses must be calculated first. So you need $3\times2 = 6$ before you can divide 9 by that result.

Absolutely! $1.5 = \frac{3}{2} = 1\frac{1}{2}$ are all correct ways to express the same answer. Use whichever form your teacher prefers!

You'd get the wrong answer! Going left to right: $9÷3 = 3$, then $3×2 = 6$. But the correct answer following PEMDAS is 1.5.

• Think of parentheses as "do me first!" signals
• Use PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction
• Always scan for parentheses before starting any problem
