a)+7+(-9)-(+5)=

b)-5+(-6):(-6)=

c)+1+(+36):(-9-9)=

d)+1+(+6)(+5-6)=

e)-6-[+3-(-5):(+5)]=

f)+8+[+4+(-7).(-9)]=​

Answer 1

$a)7 + ( - 9) - 5 = 7 - 9 - 5 = - 2 - 5 = - 7$

$b) - 5 + ( - 6) \div ( - 6) = - 5 + 1 = - 4$

$c)1 + 36 \div ( - 9 - 9) = 1 + 36 \div [ - 9 + ( - 9)] = 1 + 36 \div ( - 18) = 1 + ( - 2) = 1 - 2 = - 1$

$d)1 + 6 \times (5 - 6) = 1 + 6 \times ( - 1) = 1 + ( - 6) = 1 - 6 = - 5$

$e) - 6 - [3 - ( - 5) \div 5] = - 6 - [3 - ( - 1)] = - 6 - (3 + 1) = - 6 - 4 = ( - 6) + ( - 4) = - 10$

$f)8 + [4 + ( - 7) \times ( - 9)] = 8 + (4 + 63) = 8 + 67 = 75$
