Today in class we worked on the yellow booklet page 48.

21). (-10)+(-8)+(+6)-(+2)

First we you have to do the addition of integers, we have to combine, first the negative, then add the positive numbers.

(-10)+(-8)=-18 then add (-18)+(+6)=-12

After getting the sum, we will proceed to subtraction, that is (-12)-(+2)=-14

How did we get -14?

In subtraction of integers we have to change the sign of subtrahend so (+2) will become negative 2 then proceed to addition of integers.

(-12)-(+2)=?

(-12)+(-2)=-14

22). (-5)=(-3)=(=4)

First you have to do the addition of integers, (-5)+(-3)=-8

After getting the sum which is negative eight, we can now proceed to addition of integer (-8)=(-4)=-12 the answer is -12.
