Question

3. Find the sum of:
(i) -10, 75, 39 and -21​

Answer 1

To find the sum of all numbers, we just have to add them. So,..

$= > (- 1 0) + 75 + 39 + ( - 21) \\ \\ = > 65 + 39 + ( - 21) \\ \\ = > 104 + ( - 21) \\ \\ = > 104 - 21 \\ \\ = > \green{\boxed{ 83}}$

Therefore, we get the sum of all the numbers is 83.

Answer 2

Answer:

$=>(−10)+75+39+(−21) \\ =>65+39+(−21) \\ =>104+(−21) \\ =>104−21=>83</p><p></p><p></p><p>$
