<em><u>Explanation</u></em>:
On the left hand side of the place value chart, 20 hundreds is equal to 2 thousands because thousands is larger than hundreds. 2 thousands is 2(1000)=2000. 20 hundreds is 20(100)=2000. They are the same number.
However, on the right hand side of the place value chart, hundredths is larger than thousandths. To say that 20 hundredths is the same as 2 thousandths is incorrect, because you're saying more of a larger quantity is the same as less of a smaller quantity.
Hundredths are two places after the decimal, and have a value of 0.01. 20 hundredths is 20(0.01) = 0.2.
Thousandths are three places after the decimal and have a value of 0.001. 2 thousandths is 2(0.001) = 0.002.
We can write 0.2 as 0.200; this way we can see that 0.200 is larger than 0.002. They are not equal.
Seven thousand, eight hundred and ninety one
7000+800+90+1
Answer: 99
Explanation: 9+9 = 18
and when you switch the order of the digits, it is still 99.
Hope that helps ;)
I'm assuming you are talking about polynomials.
For example, I have x^2 + 2x + 1, and I want to add 2x^2 + x + 2
Then the like terms here are:
x^2 and 2x^2, 2x and x, 1 and 2, they are quadratic, linear and constant, respectively.
343 = 7 x 7 x 7
the answer is 7,7, and well 7
