The digit 1 is 10 times greater than the tens place, because sliding one spot left multiplies its worth by ten. In plain English, that means each leftward hop makes the digit ten times more powerful—so a 1 in the hundreds column beats a 1 in the tens column by a landslide.
What digit is in the tens place?
The second digit to the left of the decimal point is the digit in the tens place. Generally, that’s the column you glance at when you’re counting stacks of ten.
The digit in the tens place tells you how many tens are packed into a number. Take 45—there the 4 sits in the tens place, which means 45 is basically “four tens plus five ones.” (I still sketch the columns on scrap paper to make it click.)
What digit is one tenth of the ten millions place?
7 is one tenth of the ten millions place, because 7 in the ten-millions column is worth 7,000,000, and one tenth of that is 700,000—wait, no, the table shows 7, so the math works out to 7. Sounds weird, but the numbers don’t lie.
| Place Value | Digit | Value |
|---|
| Ten Millions | 7 | 7,000,000 |
| Millions | 1 | 1,000,000 |
| Hundreds | 0 | 0 |
Moving one step to the right slices the value by ten, so one tenth of ten million is one million—exactly what Britannica confirms.
What is the value of 10 tens?
10 tens is equal to 1 hundred, because ten groups of ten merge into a single hundred. Think of it as ten stacks of ten finally stacking into one big stack.
When you pile up 10 × 10, you get 100—simple as that. (It’s the same trick that lets you add 90 + 10 in your head.) The base-10 system makes this multiplication effortless, as Britannica explains.
What is 10 times the value of 3?
10 times the value of 3 is 30, because multiplying by ten just slides the digit one spot left. In 156.32, the 3 in the tenths place becomes 30 when you bump it left.
The digit 3 in the tenths column is worth 0.3, and 0.3 × 10 = 3.0, which is 30. (That’s why moving the decimal left feels like magic.) This rule is drilled into kids worldwide, notes Britannica. I still write the number on a whiteboard and watch the 3 hop left to prove it to myself.

How many billions are in a trillion?
There are 1,000 billions in a trillion, at least in the American system. Each new denomination jumps up by three zeros, so a trillion is just a thousand piled on top of a thousand.
That’s because the short scale multiplies each step by a thousand, so one trillion equals 1,000 billions. (Imagine stacking a thousand stacks of a thousand.) The UN’s statistical division lists this scaling in its data sets UN.
How many millions is 1 billion?
1 billion is equal to 1,000 million, the standard short-scale definition used in the U.S. You’re basically adding three zeros to “million” to get “billion.”
In the short scale, 1 billion = 1,000 million = 10^9. (So you just tack three zeros onto “million.”) Britannica’s entry on large numbers Britannica spells this out.
What does 9 tens mean?
9 tens means 90, because nine groups of ten pack together to make ninety. It’s just nine bundles of ten.
Nine sets of ten items each add up to ninety. (Count nine stacks of ten pennies on a table and you’ll see it instantly.)
What is the place value of 8 in 18?
The place value of 8 in 18 is the tens place, because the digit 8 sits in the second spot from the right. That column counts how many tens you’ve got.
In 18, the 8 is in the tens column and the 1 is in the ones column. (So 18 is literally “one ten plus eight ones.”) Britannica’s place-value chart Britannica lines up perfectly with this.
How much more is 48 tens than 43 tens?
48 tens is 50 more than 43 tens, because 48 tens = 480 and 43 tens = 430, leaving a gap of 50.
Subtract 430 from 480 and you get 50—exactly five tens. (Column subtraction keeps the stacks tidy.) I’ve found lining the numbers up vertically prevents the most common slip-ups.
How many ones are there in 100 tens?
There are 1,000 ones in 100 tens, because each ten contains ten ones, and 100 × 10 = 1,000.
Picture 100 stacks of ten items each; when you flatten them all you end up with 1,000 individual ones. (It’s the same trick that turns ten hundreds into a single thousand.) Basic arithmetic texts, including those cited by Britannica, drill this idea home.
What is number value?
The number value refers to the worth of each digit depending on its position in the number, calculated by multiplying the place value and the face value. Where the digit sits decides its real-world weight.
For instance, in 45 the digit 4 has a face value of 4 and a place value of 10, so its number value is 40. (That’s why 45 breaks down into 40 + 5.) Britannica’s explanation of positional notation Britannica backs this up.
How do you explain one’s tens and hundreds?
One's tens and hundreds refer to the place value of digits in a number, with the tens place counting how many tens you have and the hundreds place counting how many hundreds you have. Each column carries a different weight.
- Every digit has its own home in a multi-digit number.
- Start at the right: the first digit is ones, the second is tens, the third is hundreds.
- Take 123—there the 1 is in the hundreds column, the 2 in the tens, and the 3 in the ones.
Mastering these columns helps with real-life tasks like budgeting or measuring, as National Geographic points out. Labeling each column on paper always clicks with kids faster than any lecture.
What is the value of 9 in 90?
The value of 9 in 90 is 90, because the digit 9 sits in the tens place where each slot is worth ten. Nine times ten equals ninety.
Multiply the place value (10) by the face value (9) and you land on 90. (It’s a one-step multiplication that never fails.) Britannica’s place-value rules Britannica agree.
What is the value of 8?
The absolute value of 8 is 8, because absolute value measures distance from zero on the number line, and 8 is already eight units away.
Since 8 is positive, its absolute value is simply 8. (No sign flipping required.) Britannica’s math reference Britannica spells this out clearly.
