2•2•3•10

The expression \( 2 \times 2 \times 3 \times 10 \) can be calculated step by step:

1. First, calculate \( 2 \times 2 = 4 \).
2. Next, multiply that result by \( 3 \): \( 4 \times 3 = 12 \).
3. Finally, multiply by \( 10 \): \( 12 \times 10 = 120 \).

So, \( 2 \times 2 \times 3 \times 10 = 120 \).
