Question

Yesterday I had n baseball cards. Today I gave six away. Using n, Write an expression for the number of baseball cards I have left.

Answer 1

We use the letter n to represent the number of cards that You had yesterday.

Then, when you gave six cards away, the number of cards you have decreased by 6, i.e., now you have minus 6 cards than you had yesterday.

For example, if you had 10 cards and gave 6 away, the number of baseball cards you would have left would be:

`10-6`

Instead of 10, in this problem, we need to write "n". Therefore, the expression we are looking for is:

`\mathbf{n-6}`
