15x23?
I'd multiply it by 10 to get 230 then divide it by 2 to get 115 then add it to the original 230 which makes 345
Its much simpler.
That method just seems lengthy and annoying

The biggest lie a grade school teacher will tell you is that can't always use a calculator.
In college the only calculator you can't use is a graphing calculator which is barley needed for the test.

15x23
i would do 15x20 first =300+(15x3=45)=345
I guess my head simply works that way much better
i always shoot to multiply by a digit that ends with 0 then add or subtract the remainder of the digits such as
9x9
9x10=90(9x1)=81

This is how I learned it. IT actually looks pretty similar to the above method.

I do it this way
15 x 23
10 x 23 = 230
5 x 23 = 115
230 + 115 = 345
or
23 x 15
20 x 15 = 300
3 x 15 = 45
300 + 45 = 345
15 x 23
10 x 23 = 230
5 x 23 = 115
230 + 115 = 345
or
23 x 15
20 x 15 = 300
3 x 15 = 45
300 + 45 = 345
