Arrays and an expanded algorithm:
23 x 17
Do you have any answers for this question ,68, ,94, ,120, and the rule
23 x 17
20 x 10 = 200
3 x 7 x = 21
7 x 20 = 140
3 x 10 = 30
200+140+30+21 = 391
23 x 17 = 391
23 x 17
20 x 10 = 200
3 x 7 x = 21
7 x 20 = 140
3 x 10 = 30
200+140+30+21 = 391
23 x 17 = 391
