Question

Adauga paranteze rotunde pt a obtine din fiecare ex cate doua cu rezultate diferite: 7×6-4×4= ,9×9-9÷9= , 118-2×11+3-4×8+101×3= .

Answer 1

1. (7*6)-(4*4)=42-16=26
(7*6-4)*4=(42-4)*4=38*4=152
2.(9*9)-(9:9)=81-1=80
(9*9-9):9=(81-9):9=72:9=8
3.118-(2*11)+3-(4*8)+(101*3)=118-22+3-32+303= =96-22+3-32+303=74+3-32+303=77-32+303=
=45+303=348
(118-2*11+3-4)*8+(101*3)=(118-22+3-4)*8+303=
=(96-3+4)*8+303=(93+4)*8+303=97*8+303=...

Answer 2

(7x6)-(4x4)=42-16=26
7x(6-4)x4=7x2x4=14x4=56

(9x9)-(9:9)=81-1=80
9x(9-9):9=9x0:9=0


118-(2x11)+3-(4x8)+(101x3)=118-22+3-32+303=96+3-32+303=99-32+303=67+303=370
(118-2)x(11+3-4)x(8+101)x3=116x10x109x3=1160x109x3=126440x3=379320
