225 196

Answer 3

Sure, I'll solve the expression step by step:

15x15:

markdownCopy code
  15
x 15
-----

Multiplying the units place: 5 * 5 = 25 (write 5, carryover 2)

markdownCopy code
  15
x 15
-----
   25

Multiplying the tens place: 1 * 5 = 5 (add the carryover: 5 + 2 = 7)

markdownCopy code
  15
x 15
-----
  225

Now, let's solve the second part:

14x14:

markdownCopy code
  14
x 14
-----

Multiplying the units place: 4 * 4 = 16 (write 6, carryover 1)

markdownCopy code
  14
x 14
-----
   16

Multiplying the tens place: 1 * 4 = 4 (add the carryover: 4 + 1 = 5)

markdownCopy code
  14
x 14
-----
  196

Finally, let's subtract the second result from the first:

  225
- 196
-------
   29

The solution to the expression is 29.
