# Why is there no ones place in the decimal?

Places in the decimal system are based on powers of ten.

10^2 = hundreds

10^-2 = hundredths

10^1 = tens

10^-1 = tenths

10^0 = ones

Since zero doesn't have a negative counterpart, the ones column stands alone.

### Does the decimal point separate the tenths from the hundredths?

No. It separates the ones place from the tenths place. Examples 5.89 The decimal is between the 5 in the ones place and the 8 in the tenths place. 43.26 The decimal is between the 3 in the ones place and the 2 in the tenths place. 147.902 The decimal is between the 7 in the ones place and the 9 in the tenths place.

### Why is the ones place not called a oneths place?

The -th suffix is used to represent a fraction of a whole. Any digit in the ones place represents wholes, not a fraction of a whole; thus it is the ones and not the oneths place. Because it is to the left of the decimal point. Only the places to the right of the decimal place have the -th suffix which represents a fraction of a whole. The ones place is to the left of…

### How do you do binary counting?

Just like decimal counting except you only have two digits (0 and 1) instead of 10 (0,1,2,3,4,5,6,7,8,9). But counting is the same. In decimal you count from 0 to 9, then you start over by putting a 1 in the "tens" place and a 0 in the "ones" place. Eg., 0,1,2,3,4,5,6,7,8,9,10,11,12, etc. Same with binary, except since you only have two digits, it goes 0,1, 10 (note I put a 1 in the "two's" place)…

### What does Place value means?

the value of the place that a digit occupies in a numeral in relation to the decimal point. Examples: Ones, Tens, Hundreds, Tenths, Hundredths, Thousandths.... Each column where a number sits has a place value. In the number 125 the 1 is in the hundreds place value, the 2 is in the tens place value and the 5 is in the ones place value. More complex numbers use place values to the right of the…

### Why do you need to line up the decimal points when subtracting?

It is not a matter of aligning the decimal points, but aligning the place value columns so that the ones are under each other, the tens are under each other, the tenths are under each other, etc which is the proper way to subtract. As the decimal points are between the ones and tenths columns, with those place value columns aligned, the decimal points are aligned. Aligning the decimal points is an easy way to…

### Where is the thousandths place on big numbers?

Remember that the thousandths place is behind the zero. The thousandths place or any place value is the same no matter how big the number is. Think of the decimal as the O in ones place (hint: think of this only when you are trying to find the place value of numbers behind the decimal) Example: .123456789 So the decimal stand for ones The 2 stands for tenths 3 is for hundredths 4 is for…

### Why do you line up decimals when do you add or subtract numbers?

You are lining up the place value columns, so that the tens are under each other, the ones are under each other, the tenths are under each other, the hundredths are under each other, etc so that when you do the addition/subtraction you are adding/subtracting the tens from the tens, the ones from the ones, the tenths from the tenths, the hundredths from the hundredths, etc. The easiest way to line up the place value…
