$= 1 - 7$

$= - 6$

Answer 2

Answer:

(-6)

Step-by-step explanation:

1 + ( -7 )

=> 7 - 1 (When adding 2 integers with different signs, we must subtract both the integers regardless of the sign)

=> ( - 6 ) ( Since (-7)'s absolute value or modulus is greater than 1 and the sign of the integer was negative, we must put the negative sign to the sum.)

When we subtract two integers with different signs, i.e. one integer has a positive sign and the other integer has a negative sign, we must subtract the two numbers regardless of their signs and the sign of the integer with the greater absolute value or modulus is the sign of the sum.

Eg: 4 + (-5)

=> 5 - 4

=> (-1)

(-6) + 4

=> 6 - 4

=> (-2)

(-3) + 5

=> 5 - 3

=> 2

7 + (-2)

=> 7 - 2

=> 5

Hope this helps!!!!!!!!!!
