Answer = 9 - 14 = - 5

Step 1) is completing multiplication, which is
(-2) (-7). It involves (a) signs multiplication like (-) (-) = +
(b) number multiplication (2) (7) = 14
"(a) and (b) together is answer, which is +14"
Now complete solving as by 9 - (+14) = 9 -14 = -5
because of (-) sign in front of (+14) it becomes (-14) and when subtraction involves 'two different sign' numbers a related answer will bear "sign of large number" after a usual subtraction!
Hence (-5 ) is final answer!

remember: if there are two negative, its positive.
you can do it like this: multiply first the two negative numbers
(-2)(-7)=+14 right?
so: 9 - (+14) but negative x positive = negative
therefore: 9 - 14 = -5

use the order or operations...
remember the order:
parentheses, exponent, multiplication, division, add, subtract
so you multiply -2 and -7 first, and get 14.
9- 14 = -5... simple hope it helps
