Estimate: an approximate and reasonable answer that is close to the exact answer without actually calculating the exact answer.
Expanded Form: the display of digits to show the place value of each digit. Example 5,231 is 5,000+200+30+1
Greater Than: a symbol (>) used to compare two numbers or two quantities when the greater number or greater quantity is given first. Example: 6>4
Hundredth/Hundredths: the position of the second digit to the right of the decimal point. One of 100 equal parts. Example: 0.56, 56/100, fifty-six hundredths.
Inequality: a statement relating two or more quantities or values that are not equal using words or symbols (<,>, =)
Less Than: a symbol (<) used to compare two numbers or two quantities, with the lesser number given first. Example 4<6
