Are there numbers before 0?
Yes. They might be easier to recognize if you think of them as numbers below zero.They're called 'negative' numbers.
How do you estimate an irrational number Why might you need to be able to estimate an irrational number?
If you want to use a rational number for a mathematical operation, it will be necessary to estimate it for a numerical outcome. Irrational numbers can't be written out exactly.
What are divisibility rules used for in real life?
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
What is the answer to subtract x from 4?
Well, darling, if you want to subtract x from 4, the answer is simply 4 - x. It's as easy as pie, just like stealing the last slice of cheesecake at a party. Just remember, x might be a variable, but the result is just a good old-fashioned subtraction problem.
What numbers might be mistaken as prime?
Larger semiprime numbers are often mistaken for prime if their other factor(s) are not obvious. 40477, for instance, might appear prime at first.
Why is it necessary to regroup four and one four if you subtract three-fourths from it?
It's not necessary, but it might be helpful because three is greater than one.
Why is it sometimes necessary to regroup mixed numbers while subtracting?
because you might get mixed up
Are there numbers before 0?
Yes. They might be easier to recognize if you think of them as numbers below zero.They're called 'negative' numbers.
What are two things you have to think about when you add or subtract mixed numbers that you do not have to consider when you add or subtract fractions?
I believe there is only one difference. The mixed numbers have to be converted to fractions. After that the operation is the same. Each fraction then must have a common denominator in order to add or subtract which is true in either case. Perhaps you need to convert back to mixed number however you might have to do that also when adding fractions. Example 9/16 +9/16 =18/16 = 1 1/4. And in subtracting mixed numbers you might end up with a complete fraction thus not needing conversion. Therefore I see only one definite difference as described above on the first paragraph.
Why is meiosis necessary in organism that carry out sexual reproduction?
This is necessary because it keeps the numbers of chromosomes the same through every generation. As you might know 1 extra or 1 missing chromosome is harmful for an individual.
Is it necessary to remove wisdom teeth before orthodontic treatment?
Not really nessacary, however in might cause complications later.
Why do fractions need to have a common denomineto before you add or subtract them?
To get the right answer. If you add 1/3 and 1/4, you might not be as successful as when you add 4/12 and 3/12.
Subtracting negative and positive decimals?
By doing this it aligns all the place values so you can clearly add or subtract the correct place values and get a correct answer. You might say it is an organization technique. Of course if you use a calculator, this is not necessary.
How does it add up the score on mind feed?
I think the numbers might be random, but it might be how you answer the questions. Like if you like bagels or not, or how well you do on the screen before. not sure.........:)
Do you use and before I or is it an before I?
Well, you can use either word before I, depending on the sentence. For example: George and I went to the prom. An I is necessary in the word taint. You might be asking whether it is "a" or "an" ... if so, it is "an" because the word "I" is a vowel sound.
Why ovefishing is necessary?
Though some might say it is necessary to feed the population of the world, overfishing is not necessary.
When might i need to regroup more than one time?
You might need to regroup more than once when performing multi-digit addition or subtraction, especially when the sum or difference of two numbers exceeds the place value of the column you are working in. For example, when adding numbers like 456 and 378, regrouping may be required in both the tens and hundreds columns. Similarly, when subtracting numbers like 804 and 297, regrouping may be necessary multiple times to ensure accurate results.
