42-6x3 + (32-5x5)=
6x (24 - 14:2) - 54=
8 X 7 - 6x6=
9 +5 X 7-23 =
(100 - 35+45 - 15) x 7+(90 - 9x8)=
34 - 4 x 6:2=
32:4+ (72-36):9 +6X ( 16 + 24:4) =

----Raspuns---

Explicație pas cu pas:

56+81=137

42-18+(32-25)

24+57=81

6•(24-7)-81

6•17-54=

102-54=48

56-36=20

9+35-23=

44-23=21

(100-35+45-15)•7+(90-72)=

(75+30)•7+20=

105•7+20=

735+20=755

34-4•3=

34-12=22

8+36:9+6•(16+6)

8+4+6•22=

8+4+132=

6+132=138

Answer 2

Explicație pas cu pas:

1.56+81=137

2.42-18+32-25=31

24+32-25=31

56-25=31

3.6×(24-7)-54=48

6×24-6×7-54=48

144-42-54=48

102-54=48

4.56-36=20

5.9+35-23=21

44-23=21

6.(65+45-15)×7+90-72=683

(110-15)×7+90-72=683

95×7+90-72=683

665+90-72=683

755-72=683

7.34-24÷2=22

34-12=22

8.8+36:9+6×(16+6)=144

8+4+6×22=144

12+132=144

Spor!
