## Math Example

This week in math, I had a hard time aligning the decimals point when I was adding, subtracting, and multiplying decimals in the first ready to go on in chapter three. I learned that when your aligning the decimals, you don’t aline the numbers, but instead you aline the decimal point and fill in the extra spaces with zero’s. Once I starting doing that, it became much easier to work with decimals.

Example-pg. 116 #6

-2.66 x 0.9

so you aline the decimal points like this:

-2.66

0.90

and add an extra zero at the end of the second decimal to fill in the empty space.

Then you cross multiply like normal:

6 x 0 = 0

6 x 0 = 0

2 x 0 = 0

6 x 9 = 54

6 x 9 = 54

2 x 9 = 18

6 x 0 = 0

6 x 0 = 0

2 x 0 = 0

and the answer is 23940, then you count the places after each decimal point, which is 4 in this case, so then you count beginning at the end four spaces for the decimal point and the answer would be 2. 3940 with a negative sign at the beginning because the decimal -2.66 was negative, and whenever you multiply a negative and a positive, your answer is always a negative.

An example where you could apply this to real life would be you were buying more than one thing and you had to add the prices together to find out the total cost. For example, If you were going to buy something that costs 4.59 and something else that costs 0.54 cents, you would have to aline the decimals and add zeros, cross multiply, and then count the places after each decimal point and then put the decimal point into the answer, which in this case would be 2.4786.

Out of school

Down the hall

Up the stairs

To the locker room

Out the doors

Into the car

Onto the highway

Between the cars

Through the doors

Into the gym

Under the lights

Among the crowd

With the team

Beside my teammates

Onto the court

Within the sidelines

Near the ball

Before the server

Behind the setter

Under the ball

BUMP, SET, SPIKE! It goes over.
