Find the sum of the following integers:(a) (- 8) + (+ 5) + (- 3) + (- 2)(B) (- 7) + (- 9) + (+ 4) + (+ 3)
(a) (- 8) + (+ 5) + (- 3) + (- 2)= (- 8) + (+ 5) – (3 + 2)= (- 8) + (+ 5) – (5)= (- 8) + 0 = – 8 [ ∵ (+ a) + (- a) = 0](b) (- 7) + (- 9) + (+ 4) + (+ 3)= (- 7) + (- 9) + (4 + 3)= (- 7) + (- 9) + (+ 7)= (- 7) + (+ 7) + (- 9)= 0 + (- 9) = – 9 [ ∵ (- a) + (+ a) = 0]

The temperature on a certain morning is -11℃ at 5 a. m. If the temperature drops 3 degree at 6 a.m. and rises 5 degree at 8 a.m. and again drops 3 degree at 9 a.m. What is the temperature at 9 a.m.?
Temperature at 5 a.m. = -11℃Temperature decreased at 6 a.m. = 3℃ = -3Temperature raised at 8 a.m. = 5℃ = +5Temperature decreased at 9 a.m. = 3℃ = -3Final temperature at 9 a.m. = (-11) + (-3) + (+5) + (-3)= -11 - 3 + 5 - 3= -17 + 5= -12℃.

Using number line, add the following integers: 9 + (-6).
On the number line we first move 9 steps to the right from 0 reaching 9 and then we move 6 steps to the left of 9 and reach 3.Thus, 9 + (-6) = 3<img style="margin-left:0px;margin-top:0px;" alt="Diagram Description automatically generated" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAUUAAABNCAYAAAAxUHaEAAAQAElEQVR4AezdjZkjNRIGYH+XwV0IdyHchQAhQAgQAoQAIUAIEAKEACFACBACt283taPtbc/YbrXH9oiHmtJPqapUkr6u/pnZf/w1/hsRGBEYERgReB+BfxzGfyMCIwIjAiMC7yMwQPF9KEZhRGBEYETgcLh7UHykRfzxxx8P
