Type in
6.6 [EE] [+ -]8 [/] 3.3[EE] [+ -] 4 [=]
The [+ -] is the change sign key. It has a + on the left, a minus on the right and two rounded arrows. The top arrow goes from left to right and the bottom one goes from right to left.

Calculating chemistry 1 scientific equation divided into another?


Use the rules for exponents and you will calculate it by hand
(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3
To enter powers of 10 use the short-cut key [EE]
For example to enter 6.02*10^23 type in 6.02* [EE] 23. When you use the EE key, the base (10) should not appear.

Just got a SHARP EL-531X, it won't do simple calculations with scientific notation, It keep saying


To enter the power of 10 with exponent use the Exp key followed by the exponent. If the exponent is negative, you must use the negation key (-) not the - key (for subtraction).
When you press the Exp key you do not type in the 10.

I am trying to divide a power of 10 by and another number to a neg power of 10


For integer powers of 10 you can use the EE shortcut. [2nd][,] displays E.
For non-integer values of the exponent (such as -5.34) you must use the key sequence [2nd][LOG] (10^x) then enter your negative non-integer exponent.

How do i divide by powers of 10 in my TI-30XA calculator?


The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.

I need to find out how to use the powers button. for example 10 to the 23 power. but I don't know where the button is and how to use it.


There's a key marked "EE" (for Enter Exponent) just above the "7" key. This key is used to enter decimal exponents. To enter 1x10^23, press 1 EE 2 3

For exponents to other bases, use the y^x key just above the divide key.

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.
