MC season this year has started for me.

tasks 23544 * 34881 = 820 061 064 (correct) 41389 * 54733 = 2 265 344 137 (correct) 41345 * 54683 = 2 260 868 635 (correct) 18963 * 73434 = 1 392 528 942 (correct) I headed the ball 350x (Task 2 and 3 are quite similar because my father was so surprised that I solve the 2nd task and had problems to find another task spontaneously and so variated the last idea in his old brain.) My big challange 2019 is to solve 10 task of 3 x 3 digits while heading the ball. Multiplication of 3 x 3 digits was the "challange task" on WC 14 in Dresden. I won that challange with 10 correct solutions in 10 minutes. But I sat on a table then. Managing this while heading a ball is very hard but I think I can do that this year.

I imagine 10 minutes is a great time? I was no where close to that.
