This section may be deferred until you actually need numbers other than integers. Python can do decimal calculations, too, approximately. Try all set-off lines in this section in the Shell: As you should know, decimal representations of values can be a pain.
Expanded form decimals Video transcript I want to write this expression here as a decimal. And the first question that might pop in your head is do I multiply 4 times 1, then add 3, then multiply 1, then add 67, then multiply by 1 over 1,?
Or do I do the multiplication first? To answer that question, we just have to remind ourselves about order of operations. Order of operations, if you have a bunch of multiplication and addition in a row like this, you will do the multiplication first.
Let me put some parentheses here to remind us of that. So let's figure out what each of these expressions in the parentheses actually represent.
What's 4 times 1 million? Well, that's 4 million. What's 3 times 1,? What is 67 times 1 thousandth? And there's a bunch of ways of thinking about this. Actually, let me write them all over here. Well, I'll do the most obvious one right over here. Or we could represent this as 60 over 1, plus 7 over 1, And what's 60 over 1,?
Well, 60 over 1, is 6 hundredths. So let me put that in a different color.
So you could view this is 67 thousandths. Or you could view this is 6 hundredths and 7 thousandths. Either way, let's add all of these things together. So we have 4 million. So the 4 in the millions place literally represents 4 million. Then we have no hundred thousands. We have no ten thousands.
But then we have 3, So the 3 is in the thousands place. Let me put a comma here, so we can keep track of things. And then we have no hundreds.
We have no tens. We have no ones. We don't even have any tenths. But we do have some hundredths. We have 6 hundredths. And then we have some thousandths. We have 7 thousandths. So we put that 7 in the thousandths place.Rewrite the decimals shown in order, from least to greatest.
Includes decimals up to thousandths.
4th and 5th Grades. Read each decimal word name and rewrite the decimal in standard form. Write each number as a decimal. Part 2: Write the word name for each decimal. Part 3: Add or subtract the decimal numbers (hundredths and tenths).
Write out the new, binary number. Starting with the bottom remainder, read the sequence of remainders upwards to the top. For this example, you should have place value, zero place holder, tenth, hundredth, thousandth equivalent, equivalence Understand and use decimal notation and place value.
Read and write any number from to , knowing what each digit represents. For example, know that: Compare and order decimals Use, read and write, spelling correctly.

The real number system evolved over time by expanding the notion of what we mean by the word “number.” At first, “number” meant something you could count, like how many sheep a farmer owns.
