Question

what is 100 minus 25

Answer 1

Elizabeth,

 

Here are a few tips to help you subtract.  I assume you already know how to count and how to add.

 

100 is really also 90 + 10 , and subtract

  25 is really also 20 +  5 , so do the easier take aways (subtractions) in each column, then add the column results

-------                ---------

                         70 +  5  = 75,   so   100 - 25 = 75

 

Now, you can only add or subtract "like" things: 2 numbers, 100 apples - 25 apples = 75 apples.

But, 100 apples - 25 oranges is undefined since an apple and an orange are different.

But if a problem also says that an orange is like or equivalent in some sense to 2 apples (so defines them),

then you can perform a conversion and  100 apples - 25 oranges = 100 apples - 25(2)apples = 50 apples.

 

Hopefully, all this will help and not confuse you.

Answer 2
