There are the same number of squares in each of these two circles. Is the total number of squares even or odd?

The circle on our left has one, two, three, four, five, six purple squares. And the question told us that there are the same number of squares in each of the two circles. That means that the circle on the left [right] will also have six purple squares. Six plus six equals 12. Is the number 12 odd or even?

We know that all even numbers can be divided into groups of two. And the 12 that we have was divided into two groups of six. Because 12 is divisible by two, it is an even number. The total number of squares is even.
