Question

3.
Efectuează înmulţirea unui factor cu o sumă:
Model: 7 x (5 + 3) = 7 x 8 sau 7 x (5 + 3) = (7 x 5) + (7 x 3)
= 56
= 35 + 21
= 56
8 x (3 + 7) =
(2+ 8)x5=
2 x (4 + 6) =
7 x ( 1 + 9) =
(4+5) x 6 =
8 x ( 7 + 3) =
9 x (5+5) =
6 x (10 + 0) =
8x ( 7+5) =
2x( 9 + 4) =
6 x (10 + 3) =
9x( 8+5) =

Answer 1

Răspuns:

1:8*(3*7)=8*10=80

2::(2+8)*5=10*5=50

3:::2*(4+6)=2*10=20

4:::7*(1+9)=7*10=70

5:;;(4+5)*6=9*6=54

6:::8*(7+3)=8*10=80

7:::9*(5+5)=9*10=90

8::6*(10+0)=6*10=60si asa mai departe
