M will represent Matt and J is Jackson. M-2.25=J. You minus the difference between them and show that it equals to Jacksons. A variable is a number in math that can vary.
I would say yes and no because estimations aren't exact, they're close to the correct value. Trent's estimation is correct since 53+12=65, if we were looking for the exact distance, Trent would be wrong because there are fractions too, so the exact value would be 66 (5/12) or 65 (17/12).
Hope this helped :)
