HELP! How do you make the '='  (equals) sign on a TI 84 Calculator?!?

Press 2nd Math  to view the test menu. \n\nPress the number associated with a symbol or use the cursor keys to select one and press enter. \nThe relationship between any two numbers, expressions, lists, or matrices can be compared by selecting one of the options. A 1 will be returned if the test is true and a 0 if the test is false. For example, the test, 4 > 7, returns a value of 0 since it is a false statement. Tests can also be made on statements such as\nx = 9 or x < 2.5\n\nThe result of such a test depends upon the value of the variable x. This type of comparison is often used to control the domain over which a graph is drawn. \nWhen comparing lists and matrices, each element in the first list or matrix is compared to its corresponding element in the second list or matrix. For example, note the results of the following comparison between the two 3 element lists. \nThe {1 1 0} indicates the first two comparisons are true, while the third is false.

use an alt +{key} key ¢  \n\nalt + 0162  bam!!! you have ¢

You need 2 equals signs:\n\nif (toBeRemoved.left = null || toBeRemoved.right = null)\n\nshould be\n\nif (toBeRemoved.left == null || toBeRemoved.right == null)\n\nOne equals is for assignment, 2 for comparison.

My TI-83plus can do that...but it has to be an invertible matrix.  If the determinate is zero, then it can not be done

If you are under Windows you can turn on NumLock, and use Alt plus codes on the number pad to do some of them (Alt-253 = ², Alt-171 = ½, Alt-251 = √, etc.) \n\nAlternatively, you can use Character Map utility under Start > All Programs > Accessories > System Tools.  Then you can get lots of others:\n°±²³ΦΘΠⁿ⅓⅔⅛⅜⅝⅞∆∏∑√∞∫≈≠≤≥\n\nFeel free to copy these from here too...

when playing with < and >\nif you multiply all the equation by -1 the sign < changes to >, and the sign > changes to <\nbut if you just switch the number on the other side the sign doesnt change\nin ur case :\n2x-y < 4 \nequals\n-y < -2x + 4\nif you multiply it with -1 it will become\ny > 2x - 4\n\nlike that. hope it helps :)

hold down ALT key and type 0176 on the number keypad then relase ALT and you get °\n\ndon't use the numbers on top of the letters, only the numbers in the calculator like bit on the side work,

I just plugged this into my calculator.\n\n[1, 0, 2, 0, 2, 0 | 0\n0, 1, -3, 0, -2, 0 | 0\n0, 0, 0, 1, -1, 0 | 0\n0, 0, 0, 0, 0, 1 | 0\n0, 0, 0, 0, 0, 0 | 1 ]\n\nTake it however you want.

The symbol _ is called the underscore. You can type it by the combination Shift and - key.

Always Google! E.g., http://www.howardcc.edu/math/calculator/ti83frame.htm

depends on what version of java you are using, if that doesn't work, simply do it by line:\n\nk = 1;

It's many years since I did maths but shouldn't there be an = somewhere? And isn't there normally "y" too? I thought it would be fun to stretch my brain for a change but...Am I being obtuse?

How will you know if I use a calculator?

Many calculators now come with a backspace button.  It looks like an arrow that points to the left (←).  It is not just on Casio's or HP's.  Many TI's also have this feature.  I don't think you would find this on too many cheap calculators though.
