1 EE +- 5

EE is just above the 7, +- is just to the right of the decimal point.

1=10^0

10=10^1

100 (2 zeroes after the 1)=1x10^2

1000 (3 zeroes after the 1)=1x 0^3

1000 000 (one million) =1x10^6

1 billion =1 000 000 000 =1x10^9

100 billions =100x 1000 000 000=(1x10^2)x(1x10^9)=

1x(10^2)x(10^9)

Now use the power multiplication rule**(a^n)x[a^m)=a^(m+n)**. Thus

1x(10^2)x(10^9)=1x10^(2+9)=1x10^(11)

**100 billions =1x10^11=10^11**.

10=10^1

100 (2 zeroes after the 1)=1x10^2

1000 (3 zeroes after the 1)=1x 0^3

1000 000 (one million) =1x10^6

1 billion =1 000 000 000 =1x10^9

100 billions =100x 1000 000 000=(1x10^2)x(1x10^9)=

1x(10^2)x(10^9)

Now use the power multiplication rule

1x(10^2)x(10^9)=1x10^(2+9)=1x10^(11)

To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating

5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

Apparently you're calculating 1x10^-14 / 3.3x10^12

Note the positive exponent on the denominator. Make sure you use the (-) key to enter a negative exponent.

You need to use the (-) key in the far left column to enter negative values. Not just for exponents, but for all negative values.

If you use the exponent rules you do not need to use a

calculator for this particular case. Anyway to enter power of 10 exponents you use the [EE] key. See screen capture below.

20 [EE] (+ -)9 [X] 1[EE] (+ -) 9

Use the key labeled times 10 to power X, the one between the decimal dot ant the Ans keys, in the middle of the bottom row of keys.

10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9

To enter negative exponents use the change sign key [(-)] just above the [RCL] key

10 to -9 is entered as [x10^X] [(-)] 9 result is shown as 1x10-9.

10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9

Hello,

What you are calculating is -1 times 5^2 which is -1*25=-25.

If you want to calculate the square of -5 you enclose it between parentheses.

**Reason**

There are two operations: the power and the negation and the power has priority. Thus 5^2 is calculated first, then its negative is taken.

If you put it inside parentheses, the () has priority. The negative of 5 is taken first, then the result is squared giving 25.

**(-5)^2=25.**

Hope it helps.

Hello,

nDeriv( is valid only for real variables.

The syntax is as follows:

**nDeriv ( expression, variable, value, epsilon**)

**expression**: the function the derivative of which you want to calculate

**variable**: the name of the variable in the expression above (usually x)

**value:** the numerical value of the e x where you evaluate the derivative

**epsilon**: the numerical value of the tolerance. Default is 1x10^(-3). But you can change it to a smaller value to obtain a more precise result.

To use default value of epsilon

**nDeriv ( expression, variable, value**)

To use a different epsilon, ex 1x10^(-4)

**nDeriv ( expression, variable, value, 0.0001**)

nDeriv( A^3 , A, 5., 0.0001) should give you 75

Hope it helps.

It should be 0.01 not 0.1 coz its the inverse.I f you rewrite it, it would be like this 1/10 to the power of 2. When the power is negative it would be dividing one.

hope I help
