SOURCE: After doing this division

Hello,
The TI84 has two commands fPart( and int(. They are accesible by the sequence

[MATH][NUM][4] fPart(
[MATH][NUM][5] int(


Once you select the command it shows on home screen> you complete the command and press [ENTER]

Let the number be 15.78

int(15.78) [Sto->] [ALPHA] [F] stores the inter part of the number (15) in variable F. Similarly
fPart(15.78) [STO->] [ALPHA] [I] stores 0.78 in variable I.

Hope it helps

SOURCE: Variables

Hello,
This calculator cannot handle symbolic algebra.
Use the rules to simplify the expressions: Get rid of the parentheses using distributivity od multiplication with respect to addition; group similar terms (terms with x, terms without x).
Hope it helps.

SOURCE: Argument error whenever I type equations with variables.

Perhaps you have some data stored in the x variable.

With the calculator on, press [2nd] then the minus button. This brings up a list of all the saved data in the calculator. Look through the far left column of the list for x.

If you find x in the list, highlight x, then press F1, and then select delete.

Now it should work like normal.

Simplify the expression 0.2y3+0.3y3+0.1y3 use integers or decimals for any numbers in the expression.


All the terms in the expression have a common variable factor (y^3). factor it out to get (0.2+0.3+0.1)y^3=0.6y^3 or (6/10)y^3 or (3/5)y^3.

Give some example of math equation?


The following are examples of expressions:
2
x
3 + 7
2 × y + 5
2 + 6 × (4 - 2)
z + 3 × (8 - z)
Example:
Roland weighs 70 kilograms, and Mark weighs k kilograms. Write an expression for their combined weight. The combined weight in kilograms of these two people is the sum of their weights, which is 70 + k.
Example:
A car travels down the freeway at 55 kilometers per hour. Write an expression for the distance the car will have traveled after h hours. Distance equals rate times time, so the distance traveled is equal to 55 × h..
Example:
There are 2000 liters of water in a swimming pool. Water is filling the pool at the rate of 100 liters per minute. Write an expression for the amount of water, in liters, in the swimming pool after m minutes. The amount of water added to the pool after m minutes will be 100 liters per minute times m, or 100 × m. Since we started with 2000 liters of water in the pool, we add this to the amount of water added to the pool to get the expression 100 × m + 2000.
To evaluate an expression at some number means we replace a variable in an expression with the number, and simplify the expression.
Example:
Evaluate the expression 4 × z + 12 when z = 15.
We replace each occurrence of z with the number 15, and simplify using the usual rules: parentheses first, then exponents, multiplication and division, then addition and subtraction.
4 × z + 12 becomes
4 × 15 + 12 =
60 + 12 =
72
Example:
Evaluate the expression (1 + z) × 2 + 12 ÷ 3 - z when z = 4.
We replace each occurrence of z with the number 4, and simplify using the usual rules: parentheses first, then exponents, multiplication and division, then addition and subtraction.
(1 + z) × 2 + 12 ÷ 3 - z becomes
(1 + 4) × 2 + 12 ÷ 3 - 4 =
5 × 2 + 12 ÷ 3 - 4 =
10 + 4 - 4 =
10.

When I substract log(2) from log(4) I get .301029957, the answer should be 2, what is wrong?


The answer for the problem log(4) - log(2) is actually 0.301, so the good news is that your calculator is working properly! Here's a quick breakdown of the solution for the problem:

1) We know that log(x) = N means that 10^N = x. So in this case, we need to find a number that 10 can be raised to in order to get 4 and 2.
2) To get a better idea of what the answer to the problem will be, we look at the scale of the numbers. 4 and 2 are both smaller than 10. In order to raise any number to a power and get a smaller number, that power must be less than 1. If the power was 1 or greater, the answer would be more than 10. Therefore, we know that log(4) is a decimal less than 1 and log(2) is a decimal less than 1.
3) Now we'll simplify the problem. A logarithm rule states that:

log(x) - log(y) = log(x/y)

We can use this rule to simplify the equation in the problem.

log(4) - log(2) = log(4/2)

Since 4/2 = 2,

log(4) - log(2) = log(4/2) = log(2)

4) Now to solve the equation, the only thing that must be calculated is log(2). This would be done on a calculator. In step 2, we analyzed that log(2) must be less than 1. Therefore, the calculator is correct with the answer 0.301.

Hope this helped!

Find the value of the variable ''x'' 6x+6=4x+12


6x+6=4x+12
Since 4x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 4x from both sides.
6x+6-4x=12
Since 6x and -4x are like terms, add -4x to 6x to get 2x.
2x+6=12
Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.
2x=-6+12
Add 12 to -6 to get 6.
2x=6
Divide each term in the equation by 2.
(2x)/(2)=(6)/(2)
Simplify the left-hand side of the equation by canceling the common factors.
x=(6)/(2)
Simplify the right-hand side of the equation by simplifying each term.
x=3

Good Luck

After doing this division "7/4" I get the answer "1.75". I want to keep the whole number in one variable and the decimal part in another variable. What kind of program I could use to do that? Million of...


You may be able to find a program online that will automatically do what you want however if you don't have to do this too often you can just manually set "1" to a variable via the "STO-->" button (right above the "on" button-- select the value, pres sto-->, alpha and whatever variable you want) and set the ".75" to a variable.

Finding a program may be difficult for this type of program because you're trying to separate a whole number (essentially looking for a whole number and the remainder). You could always write a program for yourself but as I said before it might be a bit difficult.
