If 6_3 means 6-3, do parentheses first and get:

2^{2 }+ 3* 3^{2}=

then exponents!

4+ 3*9=

4+27=

2^2+3*(6_3)^2=

We have to assume that ( you might be using an old outdated computer but that's okay ) the question is

2² + 3 x ( 6 - 3 )²

Reading mathematics is a little bit different than reading English.

We discussed and you may have discussed the same lesson with your teacher or other teachers.

Math can be easy but **you must follow a set of rules or instruction(s).**

It looks like you have some **orders of and operations**.

In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.

**WARNING**

**YOU MUST FOLLOW A CERTAIN RULES OR YOU MIGHT MISCALCULATE.**

The following are orders of operations.

[ ] - BRACKETS

( ) - PARENTHESIS

DIVIDE OR MULTIPLY FROM LEFT TO RIGHT

ADD OR SUBTRACT FROM LEFT TO RIGHT

THE FOLLOWING IS AN EXAMPLE OF WHY SUCH OPERATIONS ARE IMPORTANT

IT HELPS CLARIFY A MATHEMATICAL STATEMENT

I AM ASSUMING THAT YOU HAVE A STRONG BACKGROUND AND HAVE BEEN INTRODUCED OR AT LEAST CAN FAMILIARIZE YOURSELF WITH ORDERS OF OPERATIONS

IN THE FOLLOWING STATEMENT

2² + 3 x ( 6 - 3 )²

NO BRACKETS

PARENTHESIS - YES

WE PERFORM THE OPERATION INSIDE PARENTHESIS

IN THIS CASE WE SUBTRACT 3 FROM 6

2² + 3 x ( 3 )²

OUR NEXT STEP POWERS OR SUPERSCRIPTS

WE SEE 2 OF THEM

2² WHICH IS 2 X 2 IS EQUALS 4

ANYTIME YOU SEE 2² OR 3² ETC IT MEANS MULTIPLICATION OF THE 2 OF SAME NUMBERS POWERS BY NUMBER ON TOP OF BASE NUMBER IN CASE THIS IS 2

IT MEANS MULTIPLY THE NUMBER AS MANY TIMES INDICATED

IF YOU HAD 2³ IT WOULD MEAN 2x2x2

4 + 3 x ( 3 )²

We have powers again (3)² or 3x3

4 + 3 x 9

NEXT WE DIVIDE OR MULTIPLY FROM LEFT TO RIGHT ( WE NO LONGER SEE PARENTHESIS OR POWERS )

4 + 27

NEXT WE ADD OR SUBTRACT FROM LEFT TO RIGHT

31

POINT IS AFTER FOLLOWING THE RULES OR OPERATIONS ORDERS

YOU END UP WITH THE NUMBER 31

THOSE WERE SOME POWERS

OR

THAT WAS ONE MAGICAL FULL OF POWERS MATHEMATICAL STATEMENT

You can do anything you set your mind to!

Parenthesis

Exponents

Multiply

Division

Add

Subtract

2^2+3*(6_3)^2=

2^2+3(3)^2= parenthesis

2^2+3(9)= exponents

(2×2)+(3×9)= multiply

4+27= add

PEDMAS applies here. But, unsure of what the 6_3 means.

2 and 1/3 = 7/3 miles ... 1 and 1/2 = 3/2 miles ... 7/3 = 14/6 ... 3/2 = 9/6 ... Ryan jogged 5/6 more miles on Wednesday

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The volume of each small box is 7 cubic feet and the volume of each large box is 13 cubic feet. There were twice as many large boxes shipped as small boxes shipped and the total volume of all boxes was 165 cubic feet. Determine the number of small boxes shipped and the number of large boxes shipped.

First we remember our Order of Operations which is PEMDAS. In this problem, we first do what is in the parentheses first. That is 6 - 3 = 3.

then we find 2^2 = 4

We then have 4 + 3(3)^2 = 4 + 27 = 31. Slowed down a bit we do 3 times 3 squared. That is 3 x 9 = 27. Then add 4 to that = 31.

5. On Monday, Ryan jogged 1 ½ miles in ¼ hour. On Wednesday he jogged 2 1/3 miles in 1/3 hour. How much farther did Ryan jog on Wednesday than on Monday? Write your answer as a simplified fraction.10/05/19
