1.5x1.5=2.25

2.25

It can be broken down into:

(1 + 0.5)² = (1 + 0.5)(1 + 0.5) = 1² + 1 x 0.5 + 0.5 x 1 + 0.5² = 1 + 0.5 + 0.5 + 0.25 = 2.25

Alternatively, using fractions:

1.5 = 1 1/2 = 3/2

→ 1.5² = (3/2)² = (3²)/(2²) = 9/4 = 2 1/4 = 2.25

-15 squared is equal to -15 x -15. Since multiplying two negative numbers together gives a positive number, this is the same as multiplying together 15 and 15.

Therefore, -15 x -15, or -152 = 152 = 225.
