How to multiply negative – positive numbers ?
Spending the summer getting my son ready for fourth grade math has been an interesting adventure in the amazing world of mathematics. I am not sure if I forgot most of the things I learned as a child or if math has changed so much over the years that I may be out of my depth.
For instance I ran into something I completely forgot…. How on earth do you multiply negative and positive numbers? Granted, it’s not something I use in everyday life – but my son will be learning this and he will be expecting me to help him with his homework.
My math is rusty – learn how to: multiplying negative - positive numbers.
This morning watching one of our MyWhyU math tutorials my son and I learned the basics of how to multiply negative and positive numbers. He was a bit freaked out about the whole thing but after watching the video for the second time he pretty much was able to grasp most of the concepts.
Personally, I find the time we spend together working on math – fun. I say that with a bit of reservation because it can be a bit stressful – kids are kids and it can sometimes be taxing on the nerves when my son plays dumb because he wants to run off and play video games.
Hint: playing video games is his reward for doing well. If he pays attention, takes some practice test – if he does well, he knows he can go off to kill aliens and all that.
In the weeks I’ve spent with my son – we have studied basic algebra, fractions and more. Things like commutative properties, distributive properties, the rules of how to add fractions and the rules in how to multiply negative and positive numbers.
I don’t expect him to be a math wizard – I just want him to do better in school, be prepared for all that "hard" math fourth graders like him will be facing next year. And if it means I get to spend some quality time with my son – the more the better.
