3 + 9 X 10 - 13 =
(3 + 4) x (10-5) = (25 - 15) x (100 -98) = (36-26) (15 - 9) =​

Answer 1

Răspuns:

10 x 8 - 40 = 80-40=40

9 x 5 - 40 =45-40=5

6 X 7 + 8 - 40 =42+8-40=50-40=10

3x9+ 5x 4 =27+20=47

15 + 8 x 5 =15+40=55

3 + 9 X 10 - 13 =3+90-13=93-13=80

(3 + 4) x (10-5) = 7×5=35

(25 - 15) x (100 -98) = 10×2=20

(36-26) × (15 - 9) = 10×6=60
