Well, honey, the multiplication property you're referring to is the identity property of multiplication. When you multiply any number by 1, you get that same number back. So, 42 times 1 is indeed 42. Math doesn't get easier than that, darling.

A chicken 1 a chicken equals 2 chickens then add the 2 chickens then multiply the 2 chicks then eat the chickens
6*147 = 6*(150 - 3) = 6*150 - 6*3 = 900 - 18 = 882. That uses the distributive property of multiplication over subtraction. The above is far simpler than using the distributive property of multiplication over addition 6*147 = 6*(140 + 7) but then do you know your 14 times table? I did learn it at school but if you did not, = 6*(100 + 40 + 7) = 600 + 240 + 42 = 882
If y=-42,theny = -42.QED? ? ?============Another answer:THERE it is ===> Y = -42
first do 42 divided by 7, which equals 6. 1/7 of 42=6
15
6m = 42 Divide both sides by 6: m = 7
