This video from Yay Math! is a geometry lesson on how to complete a proof involving segments. He draws a line segment with four points labeled A, B, C and D. The problem is as follows: Given: AC is equivalent to BD. Prove that AB is equivalent to CD. The first statement of proof is the given. Next, you need to define the congruent segments and state that they're equal in measurement. Next, break down the segments: AC=AB+BC, and BD=BC+CD. This is called segment addition postulate.

Here we look at squaring expressions that involve radicals because people tend to make some common mistakes while solving such expressions. Take 5 times the square root of y quantity squared, the answer here is not 5y. Here's the reason, square means to multiply something with itself so the square of 5 root y would be 5 root y into 5 root y. So 5 x 5 is 25 and under root y into under root y equals just y so the answer will be 25y.
In this tutorial the instructor talks about various strategies for solving equations and inequalities involving absolute value. To do this the first step is to isolate an absolute value. An absolute value is exactly equal to a number. If that number is less than zero then there is no solution. So, if you have an absolute value that is less than a number it means that the real value lies in between negative and positive value of that number. If your number is less than zero then it is empty se...

Taking equal groups, in our case, 7 out of the whole number, in this case 364 involves guessing. A shorter method involves taking groups, in our case, 7 out of each individual number 3, 6 and 4. If you cannot take 7 out of a number, you will subtract 0 from that number and carry down the next number. For example, you cannot take 7 from 3, so you will subtract 3-0 with the answer being 3 and carry down the next number, 6, giving you 36. You can take 5 groups of 7 out. 5 groups of 7 equals 35, ...
