Question

What does ☆ equal if the symbols below represents digits 0-9?

Answer 1

First, let's start from the sixth equation.

Since the parallelogram divided by the circle is equal the parallelogram, it means the circle has a value of 1.

Then, from the 7th equation, the pentagon minus the arrow is equal the pentagon, it means the arrow is equal 0.

From the 8th equation, the two curved arrows summed are equal 10, so the curved arrow is equal 5.

From the 2nd and 4th equations we can find that the triangle is equal 2.

Using the value of the pentagon from the 4th equation in the 3rd one, we have that 3 * moon is equal parallelogram, so the only option is:

moon = 3, pentagon = 6, parallelogram = 9.

From the 1st equation, the square is equal 8.

Finally, from the 5th equation, the arrow with circle is equal 7.

So we have:

pentagon = 6

parallelogram = 9

moon = 3

triangle = 2

arrow = 0

curved arrow = 5

arrow with circle = 7

circle = 1

square = 8

So the star is the missing algarism: 4
