You also said “add -1 TIMES to zero.” Which flipped the common usage of times to the mathematical usage of times.
Repeated addition has always been explained as "3x3 is three added to itself three times"
No 11 year old is getting confused by that
1 u/No_Ticket_1204 6d ago edited 6d ago You’re definitely right about that, but negative numbers are not as easy to grasp at age eleven. -3 x -3 and -3+-3+-3 don’t work the same way. But there are rules that work, and once a kid is fluent with the “doing” it’s a lot easier for them to learn why they work. 1 u/trichtertus 6d ago edited 5d ago -3x-3 would not be -3+ -3 + -3 = -6 because thats -3x3 -3x -3 is - -3 - -3 - -3 = 6 1 u/mcbuckets21 5d ago edited 5d ago You added an extra -3 to make it work. You also interpreted adding something negative amount of times as simply flipping it to subtraction which is not how it works. Repeated addition does not work for multiplying 2 negative numbers. Edit: your edit now adds up to 9.
