Negative Numbers and Integer Operations 3/23

ADDING AND SUBTRACTING

WHEN YOU HAVE 2 SIGNS (+ or -) NEXT TO EACH OTHER WITH NOTHING IN BETWEEN:

matching signs (- - or ++) replace with a plus sign +
so:
2++3 = 2+3
2- - 3= 2+3

non-matching signs (-+ or +-) replace with a minus sign -

so:

2- + 3=  2-3
2+ - 3= 2-3
