Question

subtract the sum of 18 and -25 from the sum of 35 ans -135

Answer 1

sum equals 18 + - 25 is equal to 18 minus 25 is equal to minus 7
again some 2 = 35 + - 135 = 35 - 135 = - 100
difference of first and second equation
= - 7 - - 100 = - 7 + 100 equals 93

Answer 2

[35+(-135)] - [18+(-25)]
= (35-135) - (18-25)
= (-100)-(-7)
= -100+7
= -93

Hope it helps.
