Question

10 × 30 = ?

Explanation:

Step1: Count the number of 30s

There are 10 green boxes labeled 30, so we are adding 30 ten times, which is equivalent to $10 \times 30$.

Step2: Simplify the multiplication

Calculate $10 \times 30$ by first computing $1 \times 30 = 30$, then add a zero at the end (since multiplying by 10 shifts the digits left by one place).
$10 \times 30 = 300$
Alternatively, using the number line: starting at 0, adding 30 ten times lands at 300.

Answer:

300
