Answer 2

a) -15+35 = 20

b) -4- (-21) = -4+21 = 17 
c) -111- (-624) = -111 + 624 = 513
d) 4,4 - (-5) = 4,4+5 = 9,4

e) -6-(-9,5) = -6+9,5 = 3,5

----------------------------------------------------------------------------------------------------------------------------------

17-(-10) = 17+10=27

-17 - 10 = -27

-17 - (-10) = -17 + 10 = -7

-13-15= -28

-13 - (-15) = -13 + 15 = 2

13-(-15) = 13+15=28

3,75 - 4 = -0,25

3,75-9-4= -8,25

-3,75-4  = -7,75

-3,75 - (-4) = -3,75 + 4 = 0,25

-66-44 = -110

45-54= -9

-9 - (-64) = -9 +64 = 55

-111-333= -444

89- (-211) = 89+211 = 300

-7,5 - (-2,5) = -7,5 + 2,5 = 5

------------------------------------------------------------------------------------------------------------------------------

6- (-3) = 9
-4 - (-3) = 1

-7 - (-17) = 10

0-(-7) = 7

-15 - (-6) = -9

-7,5 - (-2,5) = 5

 

 

 

Proszę bardzo, rozpisałam jak najbardziej mogłam. ;)
