I have a "dot" showing up after my zero, and no, it's not a decimal point. I can't make it go away. then when i try to multiply it totals the number and adds a + sign after the total mark. how do I get rid of this!!???

Hi - I think you have the "Grand Total" switch set. For normal operation set the switch to the central position as below:

There is no rule requiring a zero to the left of the decimal point, but it's generally considered good style.

You don't put a zero to the right of the decimal point unless it's significant (that is, you know that digit is not 1, 2, 3, 4, 5, 6, 7, 8, or 9).

The product is a positive number smaller than the first factor.

Sight in your scope, Loosen the set screws and zero the dials the re-set the set screws. This will make it easy for you to adjust for distance and wind from the zero setting when in the field shooting. Then you can go back to your zero.

The dot (".") on the "Total ODO" display is not decimal point, it is thousands (digit grouping) separator. If you want to set e.g. 330.75 km, then you enter "00.331". If you want to set 1145 km, you enter "01.145". The decimal point on this Sigma computer is denoted using decimal comma "," (as used in German and other lagnuages/countries) even if you set the language of the computer to English. You can see decimal comma e.g. in "TRIP DIST" display.

Near the 0 key, the calculator has the markings **dot forward slash comma in BLUE.** Thus to change the decimal mark from dot to comma or from comma to dot, press the LEFT SHIFT Blue key, followed by 0. The radix mark will toggle from one to the other.

There are 4 sig figs (sfs) in 3.414.

Also,

The rule I use is the**"dot right-moving arrow"** rule.

I know it seems weird, but it is a very powerful rule, always reliable!

__Here is what you do__:

If the number has a dot in it (that is, if it has a decimal in it), imagine an arrow swooshing from left to right through the number. Start counting sig figs as soon as the imaginary arrow strikes a non-zero digit. Every digit the arrow goes through after it hits that first non-zero digit, is a significant digit (sig fig). The total number of sig figs is the sum of the first non-zero digit + all the following digits the arrow goes through after that. Very simple, right?

As an example, in 0.00098, the arrow sweeps through the leading zeros without counting until it stikes the first nonzero digit, 9. (BONK!!) So you must count it and the following digit (8). So the total number of sfs is only 2 for this number. Try it on the other numbers for practice.

__For a better closure, I guess I should explain the other related rule for sig figs__:

The "no-dot left arrow" rule. You can use this rule when a number does__not__ have a decimal in it. For example, the number 500 s. (I am using the same unit you gave in your quantities. As you can see, no decimal is shown. So you can not be sure the number has 3 sfs or not. It would only have 3 sig figs if you were informed it was an *exact* number. An exact number is a number which has been obtained by counting every object it represents. As in a classroom filled with 200 students, each one counted by their teacher during roll call.

To apply the*no-dot left-moving arrow* rule, simply imagine an arrow moving left until it hits the first non-zero digit. In this case, that digit is the 5, which is only one digit. Therefore, there is only 1 sig fig in 500 s.

Suggestion: Google up "sig figs" and get some more examples of quantities to practice counting sig figs. Also pay attention to the important related topic of proper rounding off of calculated quantities which have different numbers of sig figs. You will find this skill invaluable when you take a lab based chemistry or physics course!

Good luck!

Step 1: Find a number you can multiply by **the bottom of the fraction** to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both top and bottom by that number.
Step 3. Then write down just the top number, putting the decimal place in the correct spot (one space
from the right for every zero in the bottom number)
Example 1: Express 3/4 as a Decimal
Step 1: We can mulitply 4 by 25 to become 100

Step 2: Multiply top and bottom by 25:

**×25**
**3**
** = **
**75**

**4**
**100**
**×25**
Step 3: Write down 75 with the decimal place 2 spaces from the right (because 100 has 2 zeros);

Answer = 0.75

Example 2: Express 3/16 as a Decimal Step 1: We have to mulitply 16 by**625** to become 10,000

Step 2: Multiply top and bottom by 625:

**×625**
**3**
** = **
**1,875**

**16**
**10,000**
**×625**
Step 3: Write down 1875 with the decimal place 4 spaces from the right (because 10,000 has 4 zeros);

Answer = 0.1875

Example 2: Express 1/3 as a Decimal Step 1: There is no way to multiply 3 to become 10 or 100 or any power of 10, but we can calculate an**approximate** decimal by choosing
to multiply by, say, 333

Step 2: Multiply top and bottom by 333:

**×333**
**1**
** = **
**333**

**3**
**999**
**×333**
Step 3: Now, 999 is *nearly* 1,000, so let us write down 333 with the decimal place 3 spaces from the right (because 1,000 has 3 zeros):

Answer = 0.333 (accurate to only 3 decimal places !

Step 2: Multiply top and bottom by 25:

Answer = 0.75

Example 2: Express 3/16 as a Decimal Step 1: We have to mulitply 16 by

Step 2: Multiply top and bottom by 625:

Answer = 0.1875

Step 2: Multiply top and bottom by 333:

Hello,

To convert from decimal to fraction and vice versa pess the [S<->D] key. Alternatively, if one of the whole numbers (integers) has decimal mark (dot) the result will be decimal.

Hope it helps.
