Multiplying and dividing integers NZ Math

This week we are learning about multiplying and dividing positive and negative numbers. The rules are a bit tricky but we will be working on understanding why things happen and looking at real world applications. Does anyone use integers? It turns out they do! For example, when we multiply two negative numbers together the product is positive When you divided by positive fractions, you learned to multiply by the reciprocal. You also do this to divide real numbers. Think about dividing a bag of 26 marbles into two smaller bags with the same number of marbles in each. You can also say each smaller bag has one half of the marbles. 26 ÷ 2 = 26(1 2) = 13 Real World Integers. When we think of Integers, or negative numbers in the real world, we usually think of being below sea level, or we may think of being at low temperatures. The following Slideshare presentation shows several other interesting applications of Integers in the Real World If you are thinking about the numbers in a day, sure you also come across this fundamental mathematical action. There are some examples: 1. We use multiplication in.

Multiplying a negative by a negative represents subtracting th.. Kahoot for Multiplying and Dividing Integers. This Kahoot game for multiplying and dividing integers includes 15 questions. A couple of them ask whether the answer would end up with a positive or negative answer. The rest of the questions are multiplying and dividing integers. Kahoot is a whole class game You see how even you can abstract operation of addition from any real world object that may be counted. You can deal with number 1 only and by adding (or subtracting number 1) you can define all integers, without even counting any real world object.
