Question
Simplify each of the following: $102 \times 103$
✓
Answer
$102 \times 103 = (100 + 2) \times 103$
$= 100 \times 103 + 2 \times 103$
$= 100 \times (100 + 3) + 2 \times (100 + 3)$
$= 10000 + 300 + 200 + 6$
$= 10506$
$= 100 \times 103 + 2 \times 103$
$= 100 \times (100 + 3) + 2 \times (100 + 3)$
$= 10000 + 300 + 200 + 6$
$= 10506$
