Answer 2

Answer:

The following is an explanation for how 7 + 8 has become 240

Let us take the number 7 and 8

Adding 7 and 8 will result in the number 15 i.e., 7 + 8 = 15

Square the resultant number 15 obtained by adding 7 and 8, now we get

15 × 15=225

Now, add 15 to the resultant number obtained by squaring the number 15

225 + 15=240

Thus, the number becomes 240 finally.
