Value of N in -8 -[2 - (6-1) - 7] = N?

Sagot :

N = -8 -2[2-(6-1)-7]


-8 -2[2-(5)-7]  --- Solve the inner parenthesis first. 6-1=5

-8 -2[2-5-7] --- Multiply the negative to 5.

-8 -2(-10) --- Solve the parenthesis 2-5-7 = -10

-8 + 20 --- Multiply -2 to -10

N = 12 --- Solve, 20-8

-8 -[2-(6-1)-7] = N
To answer this, first you must give your attention to the inner parenthesis (6-1)=5
-8-[2-5-7] = N     In this case 5 is negative because we removed the parentesis.
-8-[-10]=N
-8+10=N    since 10 is negative, removing the bracket will make it positive because negative times negative is positive.
So you will have
2=N
N=2
