An Introduction to Decimals
We can show the value represented by each digit of the decimal 98.6213 by using_____ form:
Our system of numeration is called a decimal system. In a whole number such as $2846,$ each digit is understood to represent the number of powers of 10 for its place value. The $\left.2 \text { represents two thousands }\left(2 \times 10^{3}\right), \text { the 8 represents eight hundreds ( } 8 \times 10^{2}\right),$ the $\left.4 \text { represents four tens }\left(4 \times 10^{1}\right), \text { and the 6 represents six ones (or units) ( 6 } \times 10^{\circ}\right)$. $2846=\left(2 \times 10^{3}\right)+\left(8 \times 10^{2}\right)+\left(4 \times 10^{1}\right)+\left(6 \times 10^{0}\right)$ Divide the polynomial $2 x^{3}+8 x^{2}+4 x+6$ by 2
