Solve: 0.6 × (1+2) - Order of Operations with Decimals

You actually can use the distributive property: $0.6 \times (1+2) = 0.6 \times 1 + 0.6 \times 2 = 0.6 + 1.2 = 1.8$. Both methods give the same answer!

Multiply as if both were whole numbers, then count decimal places. For $0.6 \times 3$: multiply 6 × 3 = 18, then place the decimal one position from the right to get 1.8.

That's a common mistake! You likely multiplied $0.6 \times 1 = 0.6$ first, then added 2. Remember: Parentheses always come first in the order of operations.

Yes! Use PEMDAS:

• Parentheses
• Exponents
• Multiplication and Division (left to right)
• Addition and Subtraction (left to right)

Absolutely! If your answer is 1.8, divide by 0.6: $1.8 ÷ 0.6 = 3$. This should equal what's in parentheses: $1 + 2 = 3$. It matches, so you're correct!
