Решение:

Выполним умножение:

• \( 3 \times 5 = 15 \)


• \( 5 \times 1 = 5 \)


• \( 2 \times 5 = 10 \)


• \( 5 \times 2 = 10 \)


• \( 1 \times 5 = 5 \)


• \( 5 \times 9 = 45 \)


• \( 4 \times 5 = 20 \)


• \( 5 \times 10 = 50 \)


• \( 6 \times 5 = 30 \)


• \( 5 \times 3 = 15 \)


• \( 7 \times 5 = 35 \)


• \( 5 \times 4 = 20 \)


• \( 5 \times 8 = 40 \)


• \( 9 \times 5 = 45 \)


• \( 8 \times 5 = 40 \)


• \( 5 \times 7 = 35 \)


• \( 5 \times 5 = 25 \)


• \( 0 \times 5 = 0 \)


• \( 10 \times 5 = 50 \)


• \( 5 \times 6 = 30 \)
