To determine The estimated and actual value of the given expression. Explanation Given: The expression is, 4 , 241 8 , 794 + 3 , 872 _ Procedure used: Rounding whole numbers “Step 1. Identify the place value of the digit you want to round. Step 2. If the digit to the right of the identified digit in Step 1 is 5 or more, increase the identified digit by 1 (round up). If the digit to the right is less than 5, do not change the identified digit. Step 3. Change all digits to the right of the rounded identified digit to zeros.” Calculation: Consider the numbers 4,241, 8,794 and 3,872. Clearly, the leftmost digit in 4,241 is 4, in 8,794 is 8 and in 3,872 is 3. Note that to round a number all the way, you round to the first digit of the number (the leftmost digit) and have only one nonzero digit remaining in the number. Hence, the number 4,241 becomes 4,000 as the digit next to 4 is 2 which is less than 5, 8,794 becomes 9,000 as the digit next to 8 is 7 which is greater than 5 and 3,872 becomes 4,000 as the digit next to 3 is 8 which is greater than 5

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
