Question

Write two numbers whose sum is 17 .
(A) (-1, -18) (B) (18, 1) (C) (-1, 18) (D) (18, -1)

Answer 1

Answer:

(c) -1, 18

Step-by-step explanation

If we frame the expression correctly then it becomes -

(-1) +18.

If we remember the rule of adding or subtracting integers then, we see that :

There is a( - ) symbol and a (+) symbol for both the numbers.

For integers we know that when we have a minus and a plus sign to the two numbers given the resultant operation will be subtraction, and the difference will have the sign of the greater number. Thus,

(-1) + 18 = 17.
