Did you know?

Did you know that in algebra, the expression "2 - p" can be represented by the word phrase "2 decreased by a number p"? This means that you start with the number 2 and subtract the value of p from it. Did you know that the word phrase "4 more than half Chris's age" represents the variable expression "1/2 a + 4" in algebra? This means that you take half of Chris's age and then add 4 to it. Did you know that when evaluating the expression "8p - 5" for p = 6, you get the value of 43? This means that you substitute 6 for p in the expression and perform the necessary calculations to get the answer. Did you know that the cost of 52 walks can be represented by the algebraic expression "5w + 30" and it amounts to $290? This means that for each walk, there is a $5 charge, and on top of that, there is a $30 initial fee. Did you know that a debt of 36 dollars can be represented by the number -36 in algebra? This means that the person owes 36 dollars. Did you know that a gain of five yards can be represented by the number 10 in algebra? This means that the person has gained 10 yards. Did you know that the simplification of the expression -| -27| results in the number -27? This means that the absolute value of -27 is still -27.
