Question

Simplify:

(6) 5 + [(–3) + 6]

Answer 1

5 + [(–3) + 6]
Let us first solve the subtraction in the square brackets.
Ignoring the signs, let us subtract the smaller number from the bigger number.
= 6 − 3 = 3
Since the sign of the bigger number is positive, the result will be (+3).
Now, 5 + 3 = 8
∴ 5 + [(–3) + 6] = +8
