Answer 2

Answer:

After solving the given expression, we get the solution is 91.

Step-by-step explanation:

Given: $7+7+7+7+7+7+7+7+7+7+7+7+7$

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,

$7+7+7+7+7+7+7+7+7+7+7+7+7$

Solving the above expression further we get,

$\begin{array}{l}=7+7+7+7+7+7+7+7+7+7+7+7+7 \\=14+7+7+7+7+7+7+7+7+7+7+7 \\=21+7+7+7+7+7+7+7+7+7+7 \\=28+7+7+7+7+7+7+7+7+7 \\=35+7+7+7+7+7+7+7+7 \\=42+7+7+7+7+7+7+7 \\=49+7+7+7+7+7+7 \\=56+7+7+7+7+7 \\=63+7+7+7+7 \\=70+7+7+7 \\=77+7+7 \\=84+7 \\=91\end{array}$
