18

The value of d + e + f is 14

Solution:

Given that,

d = 20

e = - 4

f = - 2

We have to find the value of d + e + f

Substitute d = 20 and e = - 4 and f = - 2

Thus we get,

d + e + f = 20 + (-4) + (-2)

Remove the parenthesis

We know that, when we multiply negative sign with positive sign, we get negative sign as result

d + e + f = 20 - 4 - 2

d + e + f = 20 - 6

d + e + f = 14

Thus value of d + e + f is 14
