Answer 1

Answer:

the sum of –2020 and 1320 is -700

Subtract the sum of –2020 and 1320 from -407.

-407-(-700) =293

the sum of —250 and 138 is -112

the sum of 136 and -272 is -136

Subtract the sum of —250 and 138 from the sum of 136 and -272

-136-(-112) = 14

Add -35 to the difference of -17 and –77.

-35+60= 25

Find the value of the following.

i. (-9) - 6+ (-5) - 7

iii. -13- [(-3) + (-15) + (-2)]

ü. (-11) + 3 – 16 + 17

iv. -13 + (-99) - (-84) + ( -5)

I.(-9)-6+(-5)-7

-9-6-5-7=-27

iii.-13-{(-3)+(-15)+(-2)}

-13 -{-3-15-2}

-13-20

-33

ü. (-11) + 3 – 16 + 17

-11+3-16+17

-27+20

-7

iv. -13 + (-99) - (-84) + ( -5)

-13-99+84-5

-117+84

-33
