hi all,
earboth you right.
I think , and maybe all that dot or period in math part that would be meant as multiply.
3 dot 5+3 dot 15
or
3(5) + 3(15) = 60
5 dot 22-5 dot 2
or
5(22) - 5(2) = 100
First you perform multiplication before you can add, as MDAS
I'm assuming you're using MDAS to represent the order in which you must process an equation?
M - Multiply
D - Divide
A - Addition
S - Subtraction
It should, in fact, be Divide first and then Multiply; ie, DMAS
Apologies if I have mis-understood you.
Personally, I was taught to use BODMAS, which is why I recognised this.
B - Brackets
O - pOwers
D - Divide
M - Multiply
A - Addition
S - Subtraction
Yeah, I accept that its only a very trivial point, but thought I should point it out in case lancemaria (or anybody, as a matter of fact) have been learning it incorrectly.
I know from experience that simple trivialities, such as this, can be very irritating when you are unable to find out where you have gone wrong.
