13) (11-16). (45 : 3²)=

14) 35: (4.3-5)=

15) 3. (15-5)=​

Answer 1

Resposta:

1) 6 + 6 + 5 = 17.

2) 28 + 4 x 5 + 5 = 53

3) 15 + 18 - 2 - 10 - 3 + 1 = 36

4) 14 + 10 - 5 = 29

5) 245 - 5 = 240.

6) 63 - 0,6 = 62,4

7) 18 + 47,25‬ - 13 = 52,25

8) 38

9) 12

10) 45 - 5 = 40

11) 12

12) 27 + 3 = 30

13) 11 - 20 = 9

14) 26,25‬ - 5 = 21,25

15) 45 - 5 = 40 (dnv?)
