-16. A negative+a negative=negative.
-40 + 70 = 30
-16+(-10) = -26
-90 (when you add a negative you simply subtract so -40-50 is -90)
40+-30=10
36 plus 40 plus negative 2 is equal to 74.
-16. A negative+a negative=negative.
3/8 + -2/5 = 3/8 - 2/5 = (3×5)/(8×5) - (2×8)/(5×8) = 15/40 - 16/40 = (15-16)/40 = -1/40 (negative one fortieth.)
It is: -16+(-14) = -30
-40 + 70 = 30
-16+(-10) = -26
-16 .
-90 (when you add a negative you simply subtract so -40-50 is -90)
-32/40 - 15/40 = -47/40 = -1 and 7/40
40+-30=10

-4 + (-16) = -4 - 16 = -20
