... Ionic compounds can be named using either of two similar methods. In order to name ionic compounds one must first understand how ionic compounds come to be. Ionic compounds are formed as a result of cations and anions which are attracted to each other because of their opposite charge and join in rat ...

... Learning Target: I can locate a point and its opposite on a number line. Important Terms: Positive Number: Any number greater than 0. They may be written with a positive sign (+) but they are usually without it. Ex 8 or +8 Negative Number: Any number less than 0. They are always written with a n ...

... of multiples of 10 that total 100. They use their knowledge of pairs of numbers that sum to 10 to identify what must be added to any two-digit number to reach the next multiple of 10. For example, they know that 56 4 60 because 6 4 10. They describe the patterns in the sequence 0 20 20, 1 19 20, pre ...

... equation we observe that the only match is when 2n ends up with 4 or 6 (and x2 ends up with 9 or 1 respectively). The exponent n can be either even or odd. Assume n is even, then n = 2k where k is an integer. Thus 2n = 22k = 4k. Four to any power has either 4 or 6 as a unit digit (this is obvious wh ...
