8-8.

How many tiles are in figure 5? If you add two tiles for Figure 6 and two more for Figure 7, how many tiles should be in Figure 7?

If there are 14 tiles in Figure 5, and you take away two for Figure 4 and two more for Figure 3, how many tiles should be in Figure 3?

Yes! If you have 14 tiles and take two away five times, how many tiles should Figure 0 have?

If Figure 0 has 4 tiles, how many times do you need to add two tiles to get to 24 tiles?
