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.
