This section gives you mixed practice with:
- addition problems:
[beautiful math coming... please be patient]
$\,x + y\,$
- subtraction problems:
[beautiful math coming... please be patient]
$\,x - y\,$
- multiplication problems:
[beautiful math coming... please be patient]
$\,xy\,$
- division problems: [beautiful math coming... please be patient]
$\,\frac{x}{y}\,$
All the answers are nonnegative.
For example, you might be asked the subtraction problem
[beautiful math coming... please be patient]
$\,7 - 3\,$,
but you won't be asked
[beautiful math coming... please be patient]
$\,3 - 7\,$.
All the answers are whole numbers.
For example, you might be asked the division problem
[beautiful math coming... please be patient]
$\,\frac{35}{7}\,$,
but you won't be asked
[beautiful math coming... please be patient]
$\,\frac{7}{35}\,$.
Since this is algebra, there might be some variables thrown in!
For example, you might be asked for
[beautiful math coming... please be patient]
$\,3x + 5x\,$ or
[beautiful math coming... please be patient]
$\,\frac{60t}{10}\,$.
Of course, no calculator is allowed!
The goal is to get confident and quick with these basic arithmetic facts.
