Question:
Evaluate. 42 + 2•7 – (5 • 4 – 15)
Answer:
First of all simplify the terms inside the parenthisis.....
where....., 5 . 4 = 20
Then,
42 + 2•7 – (5 • 4 – 15)==> 42 + 2•7 – (20 – 15)
Now, 20 - 15 = 5
==> 42 + 2•7 – (5)
Now 2 . 7 = 14
==> 42 + 14 – 5
==> 56 - 5
==> 51
So the answer is 51
Hope you understood.
