Question

1. Calculează: 143 x8+69×13= 77:7 +52 x 108= 82:2+(16X44 +26 X 103) = (25x13)+(67x14)-88:4

Answer 1

Răspuns:

143 × 8 + 69× 13 = 2041

1144 + 897 = 2041

77 : 7 + 52 × 108 = 5627

11 + 5616 = 5627

82 : 2 + ( 16 × 44 + 26 × 103 ) = 3423

82 : 2 + ( 704 + 2678 ) =

82 : 2 + 3382 =

41 + 3382 = 3423

( 25 × 13 ) + ( 67 × 14 ) - 88 : 4 = 1241

325 + 938 - 88 : 4 =

325 + 938 - 22 =

1263 - 22 = 1241
