Use │ and • to show the number 52
My daughter's first grade math homework has a practice problem that looks as follows"
"Use | and . to show the number 52"
I'm lost as to the meaning of the slash and the dot. Normally the dot would be multiplication but shes in first grade and they haven't touched times tables yet. The up down slash I'm lost on. So maybe it's something new since my calculus and finance days :P
Thanks for the help.
