Evaluate 10๐ divided by two given that ๐ equals four.

Hereโs our expression weโre told to evaluate: 10๐ divided by two. Itโs important to remember that when you see a letter right next to a number, there is an implied multiplication. So 10๐ means 10 times ๐, divided by two.

We know that our ๐ value is four. We plug in the four. We replace the ๐ with the four. And now weโre trying to say 10 times four divided by two. Moving from left to right as we multiply and divide, we would first want to multiply 10 times four. 10 times four equals 40.

The rest of the problem we copy down exactly as itโs written, divided by two. Again moving from left to right, weโre left with 40 divided by two. And 40 divided by two, 40 put in two groups, is equal to 20.

Given that ๐ equals four, 10๐ divided by two would be equal to 20.
