Answer:
hello
Step-by-step explanation:
12:(-6)+14
=-2 + 14
=12
-18:(—9)+2=
=2 +2
=4
Step-by-step explanation:
if you made no typos :
12:(-6) + 14 = -2 + 14 = 12
-18:(-9) + 2 = 2 + 2 = 4
remember :
+ + = +
+ - = -
- + = -
- - = +
that works for multiplications and divisions.
and about additions and subtractions : the first sign represents additions and subtractions with a signed 2nd operand too :
a + (+)b = a + b
a + -b = a - b
a - (+)b = a - b
a - -b = a + b
