Question

Sa = efectueze:
1. ( 14 + 8 :8 ) : 5 +5 - ( 29-3 :3 ) :4 =
2. 33 + 9 :3 × 10 - ( 60: 10 ×4 - 20 ) =
3. 99 - ( 13 +6 ×5 - 8 :4 ) + 5 x5 =
4. 63 + 3 ×4 - ( 2×2×2×2 :8+5×6)=
5 . ( 88 - 13 + 6 × 4 : 8) - ( 66 - 12 - 7 × 4 ) =

Answer 1

1)(14+1):5+5-(29-1):4=
15:5+5-28:4=
3+5-7=1

2)33+3x10-(6x4-20)=
33+3x10-(24-20)=
33+30-4=59

3)99-(13+30-2)+5x5=
99-41+25=83


4)63+12-(16:8+30)=
63+12-(2+30)=
63+12-32=43

5)(88-13+24:8)-(66-12-28)=
(88-13+4)-26=
79-26=53

Answer 2

1)(14+8:8):5+5-(29-3:3):4=
(14+1):5+5-(29-1):4=
15:5+5-28:4=
3+5-7=
8-7=1

2)33+9:3x10-(60:10x4-20)=
33+3x10-(6x4-20)=
33+30-(24-20)=
63-4=59

3)99-(13+6x5-8:4)+5x5=
99-(13+30-2)+25=
99-(43-2)+25=
99-41+25=
58+25=83

4)63+3x4-(2x2x2x2:8+5x6)=
63+12-(16:8+30)=
75-(2+30)=
75-32=43

5)(88-13+6x4:8)-(66-12-7x4)=
(75+24:8)-(54-28)=
75+3-26=78-26=52
