Question

2. Calculează:
6x5+9 x 5 =
7x5+ 8 x 5=
(6 + 3) x (10 - 5) =
(25 - 18) X (20 - 15) =
(5 x 5) + (5 x 7) - (8 x 4 + 2 x 9) =
(4 x 9) + (7 x 5) - (8 x 5 - 3 x 5) =
(9 x 4 - 3 x 8) + (5 x 6 + 3 x 4) =
(85 - 79 ) x 5 + (2 x 9) =​

Answer 2

Răspuns:

6*5+9*5=30+45=75

7*5+8*5=35+40=75

(6+3)*(10-5)=9*5=45

(25-18)*(20-15)=7*5=35

(5*5)+(5*7)-(8*4+2*9)=25+35-(32+18)=25+35-14=46

(4*9)+(7*5)-(8*5-3*5)=36+35-(40-15)=36+35-25=46

(9*4-3*8)+(5*6+3*4)=(36-24)+(30+12)=12+42=57

(85-79)*5+(2*9)=6*5+18=30+18=
