What is an antonym for equation

There are various ways that a mathematical expression fails to be an equation. It lacks a relational operator (symbol). It has a less than sign, or a greater than sign, or a combination of other symbols. If you language homework requires(?) that you find an antonym for equation, try non-equation.

Look at the color of the ALPHA key, and find if there is a second = of the same color as the ALPHA key. If there is one, you enter it as part of a mathematical equality by pressing [ALPHA] followed by the key with the second = sign marking. However, I do not see the purpose since the calculator does no accept algebraic expression. To enter a function for a table, you select the computational mode as TABLE and the calculator will display f(x)= .

How to solve an equation with negative exponent

You probably want to calculate the numerical value of some mathematical expression with numbers raised to negative exponents.
Just enter the expression as you would with positive exponents Except that before entering the value of an exponent press the change sign key, marked (-), or +/- or (+/-). Do not confuse the change sign with the usual minus sign, which is usually displayed bigger then the change sign. Make sure that the (-) is displayed before the value of the exponent. Use parentheses if necessary.

What is the meaning of the mathimatical expression

n mathematics, an expression is a finite combination of symbols that are well-formed according to the rules applicable in the context at hand. Symbols can designate values (constants), variables, operations, relations, or can constitute punctuation or other syntactic entities.
Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.
it is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have expression is there is an = sign
Yes the 6 + 1 part is an expression. Once you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence

Help please

Mathematical notation should be adhered to in order eliminate ambiguities and avoid wrong answers.

To find you 'result' I had to try different scenarii.
The one that worked is the following
  1. e^(-0.019) is 0.9811793622
  2. raise this result to the 12th power: the result is 0.7961242598
  3. Multiply this last result by 250000 to find 199031.065
The last result suggests that you made a mistake copying the final result.
This is how you should have presented the question.

Calculate 250000*(e(-0.019))^12
Notice the two set of parentheses.
To type that on your calculator
250000[*] [ ( ] [ ( ] [ Shift ] [ e] [(-)] 0.019 [ )] [ ) ] [ ^] 12

In the foregoing key sequence,
  1. every symbol between square brackets [ ] is a keypad key.
  2. Numbers are not put in brackets.
  3. [(-)] is the change sign symbol and
  4. [^] is the general power key under [VARS] and above [LN]

At least it did not take me 400 years as in the case of Fermat's theorem.
