Q. Find (a) (-6+5)÷[(-2)+1](b)(-7-5)÷12​

Answer 1

Answer:

Ans (a) 1

Ans (b) -1

Step-by-step explanation:

Ans (a) (-6+5) ÷[(-2)+1] =

-1 ÷ [-2+1]

-1 ÷ -1 = because the sign of subtraction is bigger than addition in this sum

The answer is = 1 because both signs of minus are cancelled in division.

Ans (b) (-7-5)÷12

minus minus= plus , so

(-12)÷12

-12÷12

-1, because in division one sign is visible that is minus

both sums done by the method of Bodmas
