Today we worked on the yellow booklet page 48 & 49.
These question that im doing is page 49.
11). (+15)=(-6)-(-7)
First you do addition of integers by getting the sum of (+8)+(-5)=-3
After getting the sum which is =3 we can proceed to subtraction of integers, we have to change the sign of the subtrahend, so form (-3) it will become (=3) then we will proceed to addition of integers.
step 1: (=8)+(-5)=+3
step 2: (+3)-(-3)=?
step 3:(+3)+(+3)==6
15). (+15)+(-5)-(-7)
First you will do the addition of integers by adding (+15) and (-6) and this will give +9.
The sum 9 will give us +9.
The sum 9 will be subtracted to (-7) and in subtraction of integers we need to change the sign of the subtrahend so (-7) will become (+7), then we will proceed to addition of integers.
step 1: (+15)+(-6)=+9
step 2:(+9)-(-7)=?
step 3: (+9)+(+7)=+16
The answer is +16.
