Explanation Given information: The expression is 500.34 − 123.45 . Use the below steps to subtract: Write the second number below the first number as the decimal places are lined up. Now, place the subtraction sign on the left of the second number. Now, subtract as whole numbers:- 500.34 − 123.45 _ Then, subtract the digits from the right to the left as whole numbers. Subtract the second place digits to the right of the decimal. Since 5 is larger than 4 , borrow 1 tens from 3 tens and add it to the 4 hundreds. Thus, 4 becomes 4 + 10 = 14 and 3 becomes 3 − 1 = 2 :- 500. 3 2 4 14 − 123 . 4 5 _ Subtract 5 from 14 , that is: 14 − 5 = 9 :- 500. 3 2 4 14 − 123 . 4 5 _ 9 Subtract the first place digits to the right of the decimal. Since 4 is larger than 2 , borrow 1 ones from the ones place. But since there is a 0 in the ones place, borrow 1 ten from the tens place. Since there is another 0 in the tens place, borrow 1 hundred from the hundreds place 5 . 1 hundred=10 tens Split these 10 tens as 9 tens + 10 ones . 1 tens=10 ones Split these 10 ones as 9 ones+10 tenths . Thus, in thetens place, 2 becomes 2 + 10 = 12 , the ones place digit 0 becomes 0 + 10 − 1 = 9 , the tens place 0 becomes 0 + 10 − 1 = 9 , and 5 becomes 5 − 1 = 4 :- 5 4 0 10 9 0 10 9 . 3 2 12 4 14 − 1 2 3 . 4 5 _ 9 Subtract 4 from 12 , that is: 12 − 4 = 8 . 5 4 0 10 9 0 10 9 . 3 2 12 4 14 − 1 2 3 . 4 5 _ 8 9 Now, place the decimal as in the other numbers:- 5 4 0 10 9 0 10 9

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.
