Question

Ma ajuta si pe mine cineva cu aceste exercitii va rog

Answer 1

Descopera regula si completeaza...

3. 31, 29, 27, 24, 21, 18

4. 20, 16, 12, 8, 4, 0

Completeaza casetele cu cifrele potrivite..

14 + 5 = 19

18 - 5 = 13

25 - 14 = 11

23 + 3 = 26

17 + 11 = 28

24 - 10 = 14

29 - 12 = 17

12 + 15 = 27
