If you take the square root of 16 in the first equation, you can figure out that “dog = **4**.”

Then, when you divide 36 by 4, you get that “cat x cat = 9.” Since the square root of 9 is 3, then “cat = **3**.”

If you divide 72 by 4, then by 3, you find that “bird = **6**.”

So 4 + 3 + 6 = **13**!

To solve this puzzle, you have to figure out which number gives you 125 when you multiply it by itself 3 times (or “cube” it). This reveals that “star = **5**.”

Then, when you divide 55 by 5, you find that “sun = **11**.”

If you subtract 5 from 38, you are left with 33 divided by 11 reveals that “moon = **3**.”

So when you add 11 and 3, you get the answer of **14**!

There are several algebraic ways to solve this puzzle.

Firstly, you can subtract the smiley face from the left side of the first equation. That tells you that “frowny face = (13 – a smiley face).”

Now, plug that into the third equation in place of the frowny face.

So, 13 minus a smiley face, minus the second smiley face, equals 1. Subtract the 13 from both sides, change the negatives all to positives on both sides, and divide by 2 to find that “smiley face = **6**.”

Plug 6 into the other equations to find that “frowny face = **7**.”

As with the previous problem, you can solve this equation algebraically. However, you don’t have to necessarily remember your algebra to figure it out.

You can also use trial and error. Which two whole numbers will give you 32 when multiplied?

The answers are 8 and 4, or 32 and 1. However, 32 and 1 wouldn’t make sense, as 32 is too big to be one of the hearts in the other two equations.

And since one of the hearts in the second equation has to be 8 or 4, we discover that only 4 goes in evenly, revealing that “green heart = **4**” and that “blue heart = **9**.”

This also reveals that “red heart = **8**.”

That means the answer to the problem is **4**.
