Question

(1.5 x 10^8) + ( 2.06 x 10^8) =

Answer 1

356000000

Explanation:

1. Simplify the expression

Calculate the expression inside the parentheses.

`(1.5*10^8)+(2.06*10^8)`

Simplify exponents and square roots

`(1.5*10^8)+(2.06*10^8)`

`(1.5*100000000)+(2.06*10^8)`

Perform any multiplication or division, from left to right:

`(1.5*100000000)+(2.06*10^8)\\`

`(150000000)+(2.06*10^8)`

Simplify exponents and square roots

`150000000+(2.06*10^8)`

`150000000+(2.06*100000000)`

Perform any multiplication or division, from left to right:

`150000000+(2.06*100000000)`

`150000000+(206000000)`

Calculate any addition or subtraction, from left to right.

`150000000+206000000`

`356000000`

Why learn this

Order of operations is a basic rule of algebra. It tells us what to solve first when we have an equation with multiple functions, which is something that you will likely encounter throughout your maths studies. The order is: Parentheses, Exponents, Multiplication and Division, then finally Addition and Subtraction. Remember that when you're solving within the parentheses, the Order of Operations applies!
