If the formula is to use A1 as an input, the formula should be in a different
cell. Try entering it in B1.

When place the formula =A1*.25. (If the value place in A1 is 100 than when I
put 100 into the cell I should get 75.) But when I place a value into cell A1
it overwrites my formula and leaves a value of 100 and my formula is missing.
Please advise.
