Answer:
This actually is false, it doesn't always work.
Step-by-step explanation:
Such as,
256 x 1/2 =
128.
The last digit isn't a 3, it's an 8.
Another Example,
176 x 1/2 =
88.
The last digit is also an 8 here, and not a 3.
It does work for some equations, but not for most of them, hope this helps!
