teaching addition properties
Help me and my son back to properties??
OK, so the instructions say this, "complere the sentence so that it is a application of the distributive property. "So here's the problem .... ____= 15a-20b Another is this," Answer the following questions "... 1 What is the identity element for addition? I put "+" Is this correct? 2. What is the identity element for mulitiplication? I put "x" Then theres one like this really (not me this) What is the additive inverse of 5, and what is the multiplicative inverse of -1 / 2? Finally there is a section as this ... A) indicate whether the following are enclosed or unenclosed B) Give an example for the fight against those who are not closed. 1. Whole numbers in subtraction? A )_____ b )_____ 2. Integers under multiplication? A )_____ b )_____ 3. Deivision integers? A )_____ b )_____ 4.Integers in subtraction? A )_____ b )_____ My child needs! Your teacher teaches nothing silly about this ... I will not let my child get a low grade cuz of it.
5 (3a - 4b) 1) The identity element for addition is 0. When you add 0, nothing changes. 2) The identity element for multiplication is 1. The additive inverse of 5 is -5. multiplicative inverse of -1 / 2 is -2 1) The integers are open under subtraction. 3 to 5 -2 = 2) The integers are closed under multiplication. 3) The integers will open in the division. 1 / 2 = .5 4) The integers are closed under subtraction.
