I am doing the same thing. I only have answers with the square root thing on it sorry! Maybe you will be allowed it though :S
0 = (4 + 4) - (4 + 4)
1 = (4 + 4) / (4 + 4)
2 = (4 x 4 ) / (4 + 4)
3 = (4 + 4 + 4) / 4
4 = 4 + 4 - √4 - √4
5 = √4 + √4 + {4/4}
6 = 4 + √4 + 4 - 4
7 = 4 x √4 - {4/4}
8 = 4 + 4 + 4 - 4
9 = 4 + 4 + {4/4}
10 = 4 + 4 + 4 - √4
11 = 4 / {√4 - (4/4)}
12 = {4 x 4} - √4 - √4
13 = 4! - {√4 + (4/4)}
14 = 4 + 4 + 4 + √4
15 = {4 x 4} - {4/4}
16 = {4 x 4} + 4 - 4
17 = {4 x 4} + {4/4}
18 = {4 x 4} + 4 - √4
19 = 4! + 4- (4/4)
20 = {4 x 4} + √4 + √4
Sorry about the highlighting ... if it actually shows up??? ! mean to the power of 2. / means divide. Hope it helps it doesn't help me... :) :S :(

What are the advantages of using equations?
Equations make complicated math procedures easier to accomplish and simpler to understand.
What does it mean if there are an infinite number of solutions to a system of linear equations?
Any two numbers that make one of the equations true will make the other equation true.
What are the advantages and disadvantages of equations?
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations but if you dont know your elements it can be a problem
What are solutions of trigonometric equations?
That means the same as solutions of other types of equations: a number that, when you replace the variable by that number, will make the equation true.Note that many trigonometric equations have infinitely many solutions. This is a result of the trigonometric functions being periodic.
What are the advantages of chemical equations?
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
How can you use patterns and equations to make predictions?
Using patterns and equations is a great way to make predictions. By analyzing patterns and equations, you'll have a better idea of what way your information will lay. While previous patterns and equations will not always guarantee that your new information will pattern in the same way, it should give you a more accurate predictions.
What is fractions missing number 2 equals 8 equals 20?
There are two equations in the question, both of which are wrong. There is no single fraction which will make both equations correct.
How can you make a fraction into simplest form?
You divide the top and bottom number by the same number(if you can) if you can't then u r already in simplest form
Explain why x does not necessarily represent a positive number?
x may not always represent a positive number because there are equations that make a variable a negative number
How did the Romans make ice cream?
by using the simplest of things such as snow and ice.

How can you make $25.45 using the least number of bills and coins?
When using the addition or substitution method how can you tell whether a system of linear equations has infinitely many solutions and what is the relationship between the graphs of the two equation?
If it has infinite number of solutions that means that any ordered pair put into the system will make it true. I believe the relationship of the graphs question your asking is that tooth equations will probably be the same line
