Aiden says that equivalent expressions always have the same number of terms. Is Aiden correct? If he is, explain why. If he is n
ad-work [718]
No. Because for example

4+5 is 9, which has 2 terms (4,5)
BUT
3+5+1 also equals 9, which has 3 terms (3,5,1)

Both equations are equivalent to eachother, but do not have the same amount of terms. This also goes for multiplication.

10x10 is 100, which has 2 terms

BUT

5x10x2 is also 100, which has 3 terms, therefor the answer does not determine the amount of terms in an equation.

If 1=3 2=3 3=5 4=4 5=4 then 6=?​
Mama L [17]

The value of the 6 is 3.

If you write 1 in word then you will write one and if you count the letter it will give you 3

Similarly, if you write the numbers 2,3,4,5 in word and count the number you will get 3,5,4,4 respectively.

<h3>What are the counting letters?</h3>

counting Letters provides a perfect way to introduce number words to beginning readers, as well as discuss the concepts of letters and words.

So, if you write 6 in words you will write six and on counting the letter you will get 3.

Hence, 6 = 3 ans.

Therefore the value of the 6 is 3.
