What is 25 squared?

To find 25 squared, you multiply 25 by itself, which is expressed mathematically as ( 25 \times 25 ). When you carry out this multiplication, you take the following steps:

1. Break it down into smaller components: ( 25 = 20 + 5 ).

2. Use the distributive property:

( 25 \times 25 = (20 + 5) \times (20 + 5) ).

3. Calculate using the distributive property (FOIL method):

( 20 \times 20 = 400 ) (this accounts for the first terms),

( 20 \times 5 = 100 ) (this accounts for the outer terms),

( 5 \times 20 = 100 ) (this accounts for the inner terms),

( 5 \times 5 = 25 ) (this accounts for the last terms).

4. Add those results together:

( 400 + 100 + 100 + 25 = 625 ).

Thus, ( 25^2 = 625 ). By confirming this calculation through different methods, such as repeated addition and estimation, we arrive at the correct answer
