Question about Texas Instruments TI-83 Plus Calculator

Simply press the (-) key before entering a negative number, in the same place you see the negative sign in print.

For example, to multiply 3 by -4, press 3 x (-) 4 ENTER

Please give the exact examples you were trying to graph. The syntax error points to an error in the input line, such as using the minus sign instead of the change sign (-).

Error 07 Syntax

Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign

y= (-) 1.5*x +3

Try entering it as 3 - 1.5*x

Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign

y= (-) 1.5*x +3

The function you give as example in the additional information to your duplicate post is too simple to generate an Argument error. Maybe a syntax error but not an argument error.

Check what you enter on the line that defines the function.**Do not confuse the minus sign - (for subtraction) and the change sign (negation sign) marked (-).**

You can also reset your calculator by pressing the button on the back.

Try rewriting your equations in the equivalent forms that follow.

Y1=3-X

Y2=(1-X)/3

If you do not get a syntax error it means that you were not using the correct minus sign.

If the - is the first symbol after the equal sign you must use negation (-) or change sign key.

Similarly, after the division / key you must use the negation or change sign (-)

Y1=3-X

Y2=(1-X)/3

If you do not get a syntax error it means that you were not using the correct minus sign.

Hello,

The calculator has two minus signs

Examples. Let (-) be the negation and -- the regular minus.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

The calculator has two minus signs

- The regular MINUS sign which is used with the subtraction operation. This operation is binary, requiring two operands (two terms). In a-b, a and be are the operands (they very specific names, but I will skip this detail).
- The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.

Examples. Let (-) be the negation and -- the regular minus.

- If you enter (-) 12 the TI84Plus accepts it and calculates the negative of 12.
- If you enter 12 (-) 13 the TI protests with a syntax error
- If you enter 12 ( (-) 13) the calculator interprets it as 12* (-13) and calculates -156.
- If you enter --12, the calculator displays Ans--12, where Ans is the last result calculated. If Ans happens to be 0, the new result is obviously the one you are expecting. But if Ans holds a non zero value, this is incorrect.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

- If the minus sign is the leftmost (first) symbol in your function (after the Y1=) you should use the negation. Any subsequent minus should be the regular minus --
- If the minus sign is the first symbol in an exponent, you must use the negation. Any subsequent minus in the expression of an exponent should be the regular minus --

Hello,

I am no seer, nor will I try to guess what may have happened. This error may come from various conditions

1. The most common reason is an omitted right parenthesis. For instance you press the [sin] function key. It shows as sin( , notice the right parenthesis. You enter the variable, say X, and you press [ENTER]. The calculator gives you a syntax error: It does not know what to do as long as you do not insert the closing parenthesis.

2. Another common source of this error message is the use of the regular MINUS sign instead of the (-). The latter appears on the scren as a smaller, raised minus sign. This is especially true when you want to raise a number or a variable to a negative exponent.

Every function has one way it takes in its food (argument). If you don't do it the right way, it gives you an error. The nice thing is that the calculator gives you the opportunity to correct the error. Whenever you see Error 1:quit 2: Go to, choose GO TO because the calculator shows you exactly the symbol that is creating havoc: It will be highlighted.

Hope it helps.

I think you are using the minus symbol instead of the negative symbol (located below the 3).
