Diving Decimals
Subject:
Dividing Decimals May 26, 2009 Linda Castellanos Vanessa Gonzalez First Glance At Things: There are only a few exceptions that separate dividing decimals and whole numbers. One of the main ones is that you use the position of the decimal point in the dividend to show the decimal places in your answer. The rest just falls into place. Easy First Steps Identify your divisor as a whole number or decimal. If your divisor is not a whole number, move the decimal place all the way to the right in order for it to become a whole number. Then count up how many spaces you moved it and move those same spaces on the dividend. Work It Out Now that you?ve turned the divisor into a whole number and moved up the same number of places on the dividend we?re working it out.
Concept of Imaginary Numbers
Subject:
Imaginary number = i, i = √-1
therefore, i^2 = 1
Imaginary numbers lets us find square roots of negative numbers.
For example: √-25 = 5i 3i x 5i = 15 x i^2 = -15
Because remember, i^2 = -1, so -1 x 15=-15
Imaginary numbers behave like square roots.
3i + 5 = 3i + 5, not 8i. 3i + 5i = 8i

Finding the y-intercept
Subject:
y=mx+b. b=y-intercept.
Linear Functions
Subject:
The variable in front of x would create the slope: rise over run. (rise/run) and the constant- number by itself with no variable attached- would be the y-intercept.
