Respuesta :
a. 9 + (–6) = 3
b. (–5) + 8 = 3
c. (–12) + (–6) = -18
d. 10 – (–8) = 18
e. (–4) – (+2) = -6
f. –9 – (–5) = 4
b. (–5) + 8 = 3
c. (–12) + (–6) = -18
d. 10 – (–8) = 18
e. (–4) – (+2) = -6
f. –9 – (–5) = 4
The solution to the arithmetic problem Given are :
- 9 + (-6) = 3
- (-5) + 8 = 3
- (-12) + (-6) = - 18
- 10-(-8) = 18
- (-4)-(+2)= - 6
- -9-(-5) = - 4
Kindly take note of the following arithmetic rule :
- - × - = +
- + × - = -
- - × + = -
- + × + = +
Hence,
- 9 + (-6) = 9 - 6 = 3
- (-5) + 8 = - 5 + 8 = 3
- (-12) + (-6) = - 12 - 6 = - 18
- 10-(-8) = 10 + 8 = 18
- (-4)-(+2)= - 4 - 2 = - 6
- -9-(-5) = - 9 + 5 = - 4
