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.
Volleyball
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.
