Answer:
-7
Explanation:
We have to solve this according to the B O D M A S theorem.
That is:
B ⇒ Brackets
O ⇒ Of
D ⇒ Division
M ⇒ Multiplication
A ⇒ Addition
S ⇒ Subtraction
Also, we know that,
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
( + ) × ( - ) = ( - )
Let us solve it now.
7 ÷ ( - 9 - ( - 8 ) )³
7 ÷ ( - 9 + 8 )³
7 ÷ ( - 1 )³
7 ÷ ( - 1 )
- 7
