Question

Find the sum of following
- 21 and - 5

​

Answer 1

The sum of the two numbers is -26

Step-by-step explanation:

Given:

the terms are -21 & -5

To find:

the sum of the terms

Solution:

The two terms are negative in nature

When two negatives are added and brought together we get

- 21 + (-5)

Opening the bracket and the sign changes to negative

= - 21 - 5

As there are two negatives we add both the terms

= -26

After adding the answer will always have the greater number's sign

Here, 21 is the greater number with a negative sign and hence the answer will also have a negative sign

∴ - 21 +(- 5) = -26

Thus, the sum of the numbers is -26

Answer 2

Answer:

-26 is the sum of -21 and -5.

Step-by-step explanation:

Explanation:

Given that, -21 and -5.

Here we can see that both the numbers are negative.

• And as we know, a product of negative and positive numbers is always negative. A product of two negative and two positives is always positive.

• When a group of numbers, known as addends or summands, are added together in mathematics, the outcome is their sum or total.

So, from the questions, we have, -21 and -5.

And according to the question we need to find the sum of -21 and -5.

⇒ -21 + (-5)

⇒ -21 - 5

⇒ -26.

Final answer:

Hence, -26 is the sum of -21 and -5.
