10x8 is 80. Minus 8. Is 72.
That's how I do it. I actually struggle a lot with 7x and 8x.
Still don't know 6x7 7x8 8x8 8x6
1-9 by 9 is easy though.
Take the first number, subtract 1 from it, and that will be your 10's place. Your 1's place with be whatever that first number needs added to it to get to nine.
Example... 7x9. 7-1= 6, so 60. 9-6=3. Answer is 63.
Another fun math trick while we're at it. If you want to know if a number is divisible by 3, just add up all the digits, and if that number is divisible by 3, then so is your original number. 3135...3+1+3+5=12, so 3135 is divisible by 3.
8x8 = 16x4 = 32x2 = 64

That's a nice little trick. Let's see if I can remember it. 😅
