Did it start doing it on its own? Or did this condition appear after you played some third-party game? If the last case is the correct one then the game may have reconfigured the keypad.

  1. Try to exit the game from inside the game.
  2. Remove the game from the Ram.
  3. Press [2nd][MEM][2: Mem Mgmt/Del][1:All]
  4. Use the down arrow to scroll along the list of objects in memory.
  5. Find the offending program.
  6. Use down arrow to point to the program and press [DEL].
If the program has an asterisk to the right of its name, it is archived. If you press DEL you will be asked if you want to delere it. Enter the number to the right of Yes and press [ENTER].
You may have to wait for the calculator to defragment the RAM.

    OOPS The sentence
    "If the program has an asterisk to the right of its name, it is archived."
    should read
    "If the program has an asterisk to the left of its name, it is archived."

What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

Assuming that the input numbers are given by the user:print "Menu"print "1. Addition"print "2. Subtraction"print "3. Multiplication"print "4. Division"print "0. Quit"
a = input("Please make a selection:")if a == 1: x = input("Please enter a number:") y = input("Please enter another number:") answer = x + yprint "%r plus %r = %r" % (x,y,answer)elif a == 2: x = input("Please enter a number:") y = input("Please enter another number:") answer = x - yprint "%r minus %r = %r" % (x,y,answer)
The same goes for everything else just with different signs. Don't forget that "*" is multiplication and "/" is division. Also, for 0. Just use:
elif a == 0: quit

Is there a guide of how to use this calculator i do not under stand how to work this


Here's a link to a pdf of the manual. The basics are that you have 12 white keys near the bottom, which include the 10 digits, a decimal, and the negative sign. On the right, you have the four operating keys, division, multiplication, subtraction, and addition. You also have the Enter key which will solve the expression. You'll notice that the buttons have blue and green lettering above them, and those are for the 2nd and alphabet functions. So if you press the 2nd key on the top-left, then the on key in the bottom left, then it'll turn it off, because it also functions as the off key. The Alpha key is used to input letters which are in green above each number. Good luck!

240/20x6-13+41 can't figure out the answer


You'll need to use the Order of Operations to solve this problem. They are Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (Please Excuse My Dear Aunt Sally). Multiplication/Division have the same weight, so you read it from left to right. Same with Addition/subtraction.

For this problem, you see there are no parenthesis or exponents, so you move right to multiplication/division. Reading from left to right, the first thing you see is 240/20. Evaluating that comes out to 12. Now you have 12*6 (assuming the x is a multiplication symbol), which evaluates to 72. 72-13=59, and 59+41=100.

Written another way:
240/20*6-13+41
12*6-13+41
72-13+41
59+41
100

Negative exponents? .825/(10^(-3)) ? Not sure how to get it to do the negative exponent.


You entered it correctly. Although you can leave out the parentheses if you want. The calculator will do exponents before it does multiplication or division just like it does multiplication and division before it does addition and subtraction. It has a built in order for hierarchy of operations. You only need to use parentheses if you want to do something that is different from this order. FYI, dividing by a negative exponent is the same as multiplying by a positive exponent. You could enter it in either way. .825/10^-3 = .825*10^3 = 825. I hope this helps you out.

Any formula in Excel starts with the equals sign ("="). This is how Excel distinguishes between formulas and literal values. Knowing this, you can create lots of formulas using the usual operators of +, -, * and / for addition, subtraction, multiplication and division, respectively. Please see the examples below.

Add 1 + 1: =1+1
Add the contents of cell A1 to the contents of cell B1: =A1+B1

Subtract 2 - 1: =2-1
Add the contents of cell A1 from the contents of cell B1: =B1-A1

Multiply 1 times 2: =1*2
Multiply the contents of cell A1 times the contents of cell B1: =A1*B1

I hope this resolves the question. If not, please let me know.
