3. Mathematics is the queen of science and Arithmetic is the queen of Mathematics

4. Find the result of: -5 -4 -3 -2 -1 1 2 3 4 5
Find the result of:
2 + 3; 2 + (–3); –2 + 3; –2 + (–3)
2 – 3; 2 – (– 3); – 2 – 3; –2 – (–3)

5. Calculate 2 + 3 2 1 -1 2 -2 3 -3 4 -4 5 -5 3
So, = 5

6. Calculate 2 + (–3) 2 1 -1 2 -2 3 -3 4 -4 5 -5
– 3
So, 2 + (– 3) = –1

7. Calculate –2 + 3 –2 1 -1 2 -2 3 -3 4 -4 5 -5 3
So, – = 1

8. 1 -1 2 -2 3 -3 4 -4 5 -5 Calculate –2 + (– 3) – 2 – 3-1 2 -2 3 -3 4 -4 5 -5
– 3
So, – 2 + (– 3) = – 5

9. Calculate 2 – (–3) 2 1 -1 2 -2 3 -3 4 -4 5 -5
–(– 3)
So, 2 – (– 3) = 5

10. Calculate 2 – 3 2 1 -1 2 -2 3 -3 4 -4 5 -5
–(+3)
So, 2 – 3 = –1

11. Calculate – 2 – 3 -2 1 -1 2 -2 3 -3 4 -4 5 -5
– 3
So, – 2 – 3 = – 5

12. 1 -1 2 -2 3 -3 4 -4 5 -5 Calculate – 2 – (– 3) – 2 – 3-1 2 -2 3 -3 4 -4 5 -5
– 3
So, – 2 – (– 3) = 1
