Question

20+20+20+20+20+20+20+20+20+20​

Answer 1

Answer:

Hey mate here is your answer :

Here we can do it by two methods let me show you :

First is that we should take common 20 because all is same so :

20(1+1+1+1+1+1+1+1+1+1)

20(10)

200.

Another method is that we should add them all :

20+20+20+20+20+20+20+20+20+20

(20+20+20+20+20) + (20+20+20+20+20)

(100) + (100)

200.

Thus the answer is 200 .

Hope it helpful to you mate if you satisfied than please mark me as brainlest ☺ ✌

Answer 2

Answer:

The solution of the given expression is 200.

Step-by-step explanation:

Given: $20+20+20+20+20+20+20+20+20+20$

We have to solve the above expression.

• As we know that, adding two or more numbers together is known as an addition.
• The addition is denoted by a symbol(+).

Following are the properties of addition:

1. Identity property of zero.

2. Inverse property.

3. Commutative property.

4. Associative property.

We are solving in the following way:

We have,

$20+20+20+20+20+20+20+20+20+20$

Solving the above expression further we get,

$\begin{array}{l}=20+20+20+20+20+20+20+20+20+20 \\=40+20+20+20+20+20+20+20+20 \\=60+20+20+20+20+20+20+20 \\=80+20+20+20+20+20+20 \\=100+20+20+20+20+20 \\=120+20+20+20+20 \\=140+20+20+20 \\=160+20+20 \\=180+20 \\=200\end{array}$

In this problem, we are assuming we have to solve the given expression.
