You can use PEMDAS to solve order of operations!

Which means, "Please Excuse My Dear Aunt Sally".

P= Parenthesis

E= Exponents

M= Multiplication

A= Addition

S= Subtraction

Here is an example of how to solve order of operations:

1×1+2-(12-1)

First: (12-1) = 11

Second: 1×1=1

Third: 1+2=3

Fourth: 3-11=8

The answer would be 8.

During a storm one and five hundredths inches of rain fell near Marie's house which shows the amount of rain in standard form?
Rudik [331]

Answer:

1.05 * 10⁰

Step-by-step explanation:

Standard form is a way of representing either very large or very small numbers easily.

If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).

Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.

Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05

Amount of rain in standard form = 1.05 * 10⁰
