Question

Find the successor and the predecessor of -19
Subtract the sum of -235 and 137 from - 152.
What must be added to - 176 to get -95​

Answer 1

Answer:

s= -18, p= -20 is the answer

Answer 2

Answer:

successor of -19 = -18

predecessor of -19 = -20

sum = -235 + 137 = -98

subtract = -152 - (-98)

-152 + 98

= -54

let number to be added be x

so according to question,

-176 + x = -95

hence, x = 81
