Answer 1

ex 1

: 4×5........35, 3×9=27, 9×4.....32, 7×4=28, 8×4.....36,4×6....21, 9×4=36, 8×3.....23...., 5×4.......6×2,4×4......3×4,

4×6=24,2×9= 9×2.

ex 2

9×4-25 = 36 -25 = 11

4×5-15= 20-15 =5

1×4+35= 4 +35=39

4×3+39=12+39=51

36+4×7=36-28=8

81-6×4=81-24=57

si tot asa Crede-mă nu sunt grele de loc si celelate le poti face cum ti le Am făcut eu si tu te iei dupa exemplu
