2) -7 - (-9) = +2
3) -3 - (-7) = +4

Partitive Division is when you divide it into parts
Qoutative Division - Sharing with group
Chapter 4
Order of Operation with Integers
To solve problem like these:
-24+[(-8)/(+4)]=
(+5) x (-3) + (-6) ÷ (+3)=
You'll have to use BEDMAS
Brackets, Exponents, Division, Multiplication, Addition, and Subtraction
Good job, Jieram! I liked how you described BEDMAS. Next time add a link or video.
