Question

Subtract: a. 14 – 7 – 5 b. (35 – 20) – 3 c. 45 – (23 – 14) d. 56 – 32 – 5

Answer 1

Answer with explanation:

We are asked to simplify the expression that is given each of the four options.

a)

`14-7-5`

We know that we need to first sum of 7 and 5 since they are the terms with the same sign i.e. negative sign.

Hence, on adding we get
`7+5=12`

Now we subtract this quantity by 14 to get:

`14-12=2`

Hence, the answer is : 2

b)

`(35-20)-3`

Now we first solve the parentheses term.

i.e.

`35-20=15`

and

`15-3=12`

Hence, the answer is: 12

c)

`45-(23-14)`

Now again using the rule of PEMDAS we first solve the parentheses term.

i.e.

`23-14=9`

and on subtracting this quantity by 45 we get:

`45-9=36`

Hence, the answer is: 36

d)

`56-32-5`

We first add 32 and 5 since they are the terms with the same sign.

Hence, we get:

`32+5=37`

and now on subtracting this term by 56 we get:

`56-37=19`

Hence, the answer is: 19

Answer 2

a. 2

b. 12

c. 36

d. 19

Explanation:

a. 14 – 7 – 5 = 14 - 12 = 2

b. (35 – 20) – 3 = (15) -3 = 15 - 3 = 12

c. 45 – (23 – 14) = 45 - (9) = 45 - 9 = 36

d. 56 – 32 – 5 = 56 - 37 = 19

Hope it helps.

Thank you..!!
