Answer 1

Răspuns:

Explicație pas cu pas:

7x8 - 5x8 = 56 - 40 =16

(7-5) x 8= 2x 8=16

24 : 4 - 16 : 4 = 6 - 4 = 2

( 24 - 16) : 4 = 8 : 4 = 2

23 x 3 + 11 x 3 = 69 + 33 =102

(23+11) x 3 =34 x 3 =102

98 : 7 - 28 : 7 = 14 -4 = 10

(98-28) : 7 = 70 : 7 =10

6x7+8x7-5x7=42+56-35=63

(6+8-5) x 7=9 x 7=63

(123+324) x 2= 447 x 2=894

123 x 2 + 324 x 2 = 246 + 648 =894

5 x (34+89) = 5 x 123 = 615

5 x 34 + 5 x 89 = 170 + 445=615

(2143 -567) x 4 = 1576 x 4 =6304

2143 x 4 - 567 x 4 = 8572 - 2268=6304

7 x (998-876)= 7 x 122 =854

7 x 998 - 7 x 876 = 6986 - 6132 =854

(48+40-36) : 4 = 52 :4 =13

48 :4 +40 : 4 -36 : 4= 12+10 - 9 = 13
