7. 18 - 6 ÷ 2 + [(-5) * (-4) - {3 - (3 - 5)}]
Answers
Answer:
we evaluate the given numerical expression as follows:
18 - [6 - {4 - (8 - 6 + 3)}]= 18 - [6 - {4 - (2 + 3)}]
=18 - [6 - {4 - (5)}]
=18 - [6 - {4 - 5}]
=18 - [6 - {-1}]
=18 - [6 + 1]
Note: Subtracting a negative number, e.g., -1, is the same as adding its opposite, e.g., positive 1 or 1, as shown in the previous step.
=18 - [7]
=18 - 7
= 11 is the result or final answer.
Answer:
30
Step-by-step explanation:
18-6/2+[(-5)*(-4)-{3-(3-5)}] =18-6/2+[(-5)*(-4)-{3-(-2)}]
=18-6/2+[(-5)*(-4)-{5}]
=18-6/2+[20-{5}]
=18-6/2+[15]
=18-3+15
=15+15
= 30
