Question

Efectueaza :
1. (88-13+6×4:8)-(66-12-7×4)=
2. 48+(73-65)×6+(24+24:3)=
3. ( 8×5:10+6×6)-(10+3×3)=

Answer 1

1)(88-13+6x4:8)-(66-12-7x4)=
(88-13+24:8)-(66-12-28)=
(88-13+3)-(54-28)=
78-26=52

2)48+(73-65)x6+(24+24:3)=
48+8x6+(24+8)=
48+48+32=
96+32=128

3)(8x5:10+6x6)-(10+3x3)=
(40:10+36)-(10+9)=
4+36-19=
40-19=21

Answer 2

(88-13+6x4:8)-(66-12-7x4)=(75+24:8)-(54-28)=78-26=52 48+(73-65)x6+(24+24:3)=48+8x6+32=48+48+32=96+32=128 (8x5:10+6x6)-(10+3x3)=40-19=21 Sper ca te-am ajutat!
