SOURCE: Addition Problem with HP 17BII

do a self test

1. Turn the calculator on.
2. If you have the optional infrared printer, turn it on. Certain diagnostic
information is printed during the test.
3. If possible, return to the MAIN menu (press @A).
4. To start the self-test, hold down C while you press the fifth menu
key from the left. Once the self-test has begun, do not press any keys
until you are ready to halt the test.
5. During the test, the calculator beeps periodically and displays various
patterns and characters. Watch for one of two messages that are
displayed before the test automatically repeats:
􀂄 If the calculator passes the self-test, the calculator displays
        
􀂄 If the calculator displays     followed by a five-digit number,
the calculator requires service.
6. To halt the self-test, hold down C while you press the third menu
key from the left. The calculator displays             . If you
press any other key instead, the test halts and the calculator displays
a     message. This results from an incorrect key being pressed,
and does not mean that the calculator requires service.
7. If the calculator failed the self-test, repeat steps 4 through 6 to verify
the results. If you do not have a printer, write down the messages that
are displayed in step 5.

Adjust the screen contrast. Turn the calculator on. Press and release the 2nd key, then press and hold the up-arrow key until the numbers darken. If you go too far, repeat the process with the 2nd and down-arrow keys.

Phasor addition on classpad 330

Open up keyboard, go to 'cat' tab and scroll down to get ' <( ' symbol.

Input the magnitude followed by angle separated by a comma (E.g. <(15,10) ). The first element in the bracket is the magnitude of the phasor while the second element is the angle.

To do phasor addition simply add more of the '<(' symbol. (E.g. <(15,10) + <(12,5) is the addition of phasor_1 with magnitude 15 and angle 10 and phasor_2 with magnitude 12 and angle 5 ).

Note: the symbol ' <( ' appears at the very bottom of the list and the '<' symbol is actually more flat in appearance like how a normal phasor is usually represented.

Addition meaning and properties

I suppose you have 5 fingers in each hand.
If you put your two hands together, you make a new set of fingers out of the first two (the hands)
How many fingers in the new set, count them: 10. When you count by 1, you are in fact adding 1 to the previous result
You could see this new number of fingers as some combination (putting together, gathering) of the two numbers 5.
Mathematically you call this operation (combination) addition
The simplest things are sometimes the hardest to explain, or put into words.
Terminology: words
Let a and b be two numbers (Please do not ask me about their values: make up your own.)
The addition operation is symbolized by the + sign.
Addition of a and b, or of b to a is written as a+b.
The result of the operation is called its sum
If I write a+ b= c, where c is some number
b is called the addend ( it is short for addendum), c is the sum . For some authors both a and b are called addends. You could say that any number involved in an addition (operation) is an addend.

2+3= 3+2=5
For arbitrary numbers (numbers you may choose), you can write
The order of the terms (which comes first, and which second) has changed but the result is the same. This is a property that is common to (shared with) all additions. It has received a scientific name, commutativity.
The addition is a commutative operation and we write a+b=b+a

Now imagine you have to add three or more numbers
2+5 +17
You can do that in two steps
Add 2 and 5, then add the result to 17
You can also add in another way: add 5 and 17, then add the result to 2, which you write as 2+(5+17)
Let's compare the results of the two ways
2+ (5+17)=2+22=24
The two sums are identical. (2+5)+17=2+(5+17)=24
For other undisclosed numbers we can write
(a+b)+c=a +(b+c)

This property is verified by all sets of three numbers. It is a general property called associativity

There is another property
Neutral element.
In every set of numbers that has addition as a rule there is an element, call it e, such that
for any number a of the set a+e=e+a=a
the element e is called the neutral element, in that when added to a number it gives you back that number. For real numbers, the neutral element is the number 0.
Summary of words introduced :
To add, addition, terms, addends, result, sum, commutativity, commutative property, associativity, associative property, neutral element.
I will stop here, believing that you have ADDED many new terms (words) to you vocabulary.

How do I add Exponents on my T1-30xa calculater

There is a rule of Algebra, that says
(a^m)[x] (a^n) = a^(m+n)

a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.
If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.
If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10.

I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as
2^7 + (5.5^3) - (1/3)^4

Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied

For the exemple above
2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543

For the cube of 5.5 you can use the key combination [2nd][X^3]

Hope it helps.
