because -4 x a = -8, so a = -8 : -4 = 2
because 2 x b = 10, so b = 10 : 2 = 5
because -4 x 5 = -20, so c = -20

USE IT! Work in groups. Look at Wassily Kandinsky’s painting Squares with Concentric Circles. Choose two squares in the painting and say how the colours in each square are related. Which square do you like best and why?

A: (Square 3) Red and yellow are harmonious colors. Red and blue are complementary colors. I like square 5 because it looks impressive. It reminds me of my eyes.
B: (Square 9) Blue and green are harmonious colors. Green and red are complementary colors. I like square 9 because it looks like harmony and peace. It reminds me of images of the earth or a forest around the lake.
