I have created a simple worksheet to help my kids practice math facts using
the "randbetween" function, but I also have an IF-THEN-ELSE to show them if
they are right. The problem is that as soon as they enter their values, new
values are generated and their answer is no longer correct. I went into the
options and made calculations manual, but then the answer is not updated
either.

Is there an easy way to select cells to update automatically (or after
pressing a button with a macro) while leaving the others with their original
values?
=randbetween(-12,12)
x =randbetween(-12,12)

=IF(B3=B1*B2,"Great!","Try Again")

I would like cells B1 and B2 to only be updated manually, but I would like
B4 to be updated either automatically or when they are finished with a sheet
and hit a button that says "Check answers" or something like that.

Thanks!
