Hi every one!
I have been teaching math, additional math and physics for 3 years now and I found that there are a few tricks that I've learned to speed up and minimize how we get answers to our mathematical problems.
I found that the basic + - * / of the plus minus multiply and divide rule are not fully understood by students.
So what is this plus minus multiply and divide rule? Simple its how you arrange an equation to ensure that you get your answers in a proper manner.
Let me elaborate this method.
+ - * /
1) arrange all the items in an equation so that it fits the above sequence.
let the equation of
-5 * 2 - 3 / 6 + 4
make sure the brackets are placed accordingly
(-5 * 2) - ( 3 / 6 ) +4
then arrange them with the sequence + - * /
+4 - ( 5 * 2) - ( 3 / 6 )
then solve starting with the right of the sequence thats / * then - +
+4 - ( 5 * 2) - ( 0.5 )
+ 4 - 10 - 0.5
thus the end it will only be plus and minus which is far easier that a mixed equation of all 4 operand.
and the answer is - 6.5
Thats all ;)
If there are any typo's it could be my keyboards battery so do leave a comment. Thank you
