What is the answer to : 20 / 2(5+5)

100

Explanation:

Before we begin, you should remember the order of operations from left to right:

1- Parentheses

2- Exponential

3- Division/multiplication

4- Addition/subtraction

Now , the given is:

We will start by resolving the brackets:

5+5 = 10

Therefore, the expression now is:

Note that multiplication/division both have the same rank in the order of operations. This would mean that we will go from left to right and resolve whichever of them comes first.

In our expression, we can see that division comes first. So, we will start by division:

The expression now became:

10 * 10

We will finally do the multiplication:

This would give us the final answer 100.

Combining all the above steps:

Hope this helps :)

a negative exponent is translated as follows:

so, we have

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
