Since they are whole numbers you can just subtract 255 – 245 = 10 The ^2 means add two decimal points after the 10 in the positive direction since it’s ^+2

Since they are whole numbers you can just subtract

255 – 245 = 10

The ^2 means add two decimal points after the 10 in the positive direction since it’s ^+2

So 1000

255^2 =25500

245^2 = 24500

25500 – 24500 = 1000

5000
