Given the position of a, B and C on the number axis, as shown in the figure, simplify | a | a + | B | B + | C | C | Math enthusiast | Mathematical art

Given the position of a, B and C on the number axis, as shown in the figure, simplify | a | a + | B | B + | C | C

It can be seen from the figure that a > 0, b > 0, C < 0, so | a | a + | B | B + | C | C = AA + BB + − CC = 1 + 1-1 = 1
