Question
State which is greater:
$(8 + 9) × 10$ and $8 + 9 × 10$
$(8 + 9) × 10$ and $8 + 9 × 10$
✓
Answer
$\Rightarrow (8 + 9) \times 10 = 17 \times 10$
$\Rightarrow (8 + 9) \times 10 = 170$
$\Rightarrow 8 + 9 \times 10 = 8 + 90 = 98$
$(8 + 9) \times 10 > 8 + 9 \times 10$
$\Rightarrow (8 + 9) \times 10 = 170$
$\Rightarrow 8 + 9 \times 10 = 8 + 90 = 98$
$(8 + 9) \times 10 > 8 + 9 \times 10$
