Answer 1

Explicación paso a paso:

4 + 5 x 8 =4+40=44

12-5x 4 =12-20= -8

25 x 1 + 25 =25+25=50

8 + 4 - 3 x 10 =8+4-30=12-30= - 18

7x3+5= 21+5=26

-24 + 6 x 2 = - 24+12= -12

2 + 5x 4-4x2 =2+20-8=22-8=14

72 + 3x5-8 +2=72+15-8+2=87+7=94

82 - 12 + 4 + 52 =70+56=126

32 + 5x 3 + 12 + 4 =32+15+16=63

42 + 2 x 3 +8 =42+6+8=56

52 - 15 +3 + 62 =37+65=102

12 + 4x3 - 24 =12+12-24=24-24=0

20 - 5 x 4 + 20 =20-20+20=20

102 + 10- 100 =112-100=12

5 + 4 + 3x6 =9+18=27

52 - 25 =27

3.5+ 2.5 x 1.2 =3.5+3=6.5

0.4 x 5.1 + 7.2=2.04+7.2=9.24

25 + 32 + 4 =61

3.2 + 4.3 x 2.5 =3.2+10.75=13.95

8.5-2.1 x 3.3 =8.5-6.93=1.57
