## We are already familiar with representing time in __base 60__.

Play around with the clocks to see the different ways we represent seconds.

Use the **up** arrow on your keyboard to **add 1 second, minute, or hour.**

Use the **down** arrow to **subtract 1 second, minute, or hour.**

Use the **right and left** arrows to **switch between the clocks.**

**Total:**

**seconds**

Notice how the clocks fill up from right to left and how each clock **grows by a factor of 60.**

We can also represent these same bases using **exponents of base 60!**

Each tick adds **60 ^{2} seconds,**

which is

**3,600 seconds,**

which is

**one hour.**

Each tick adds **60 ^{1} seconds,**

which is

**60 seconds,**

which is

**one minute.**

Each tick adds **60 ^{0} seconds,**

which is

**one second.**

**Total:**

**seconds**

## We are used to counting in __base 10__.

Play around with the clocks to visualize our conventional counting system.

Use the **up** arrow on your keyboard to **add by 1, 10, or 100.**

Use the **down** arrow to **subtract by 1, 10, or 100.**

Use the **right and left** arrows to **switch between the circles.**

**Total:**
