Given that | a | = 2, | B | = 2, | C | = 3, and the position of rational numbers a, B, C on the number axis is shown in the figure, then a + B + C=______ .

Given that | a | = 2, | B | = 2, | C | = 3, and the position of rational numbers a, B, C on the number axis is shown in the figure, then a + B + C=______ .

According to the position of rational numbers a, B, C on the number axis, B < 0, a > 0, C > 0, ∵ | a | = 2, | B | = 2, | C | = 3, | a = 2, B = - 2, C = 3, a + B + C = 2-2 + 3 = 3
