Using algebra in your everyday life

I was never any good at maths so someone will no doubt put me right but I would have thought something like:

500 -(m+c) divided by (I cant see a division sign on my keyboard)b
where m= cost of milk in cents; c= cost of cerealin cents & b= cost of 1 banana in cents

starting with $5, take away the cost of the milk and cereal, divide the amount of money left by the cost of a single banana to give the number she can buy

so, if milk was $2 & cereal $1 she'd have $2 left
if bananas were 50c each, she could get 4
(you may have to work in cents though)
this is probably absolute rubbish but I had to have a go

Boo, wish i could help u but i hated algebra & failed it in school & had to take it over because it was a required subject to graduate. I have never had to use it one time since i graduated & knew i wouldn't when i was having to take it. I hope u can find someone who can help you. HAPPY DAYS TO U.

Ugh, math, and mental math at that. I'm not sure how to write the equation, sorry. I don't use math in my everyday life, especially not Algebra. If I did have to use math that required formulas I would have them already programed into my computer so I could just plug in the numbers and let it tell me what the answer is.

Algebra is easily the biggest irritant to me in school. I don't understand it and God knows I have tried.

There is nothing for my brain to grab.

Trig is triangles. I understand triangles. I can see them in my head. Algebra is nothing.

And I fell off the algebra bus in grade 8 when I could not answer the question; "A+B=5"

I went 1+4, 4+1, 2+3, 3+2...decimals, fractions and was still marked wrong. I have never recovered from that blow.

I have looked for help in every corner and still nothing makes sense. I gave up.

I have not a clue. Math is not my strong suit. But I do know that performing algebra in my head is much easier than a written formula. Of course, you don't get credit for what's in your head.

Isn't the answer 2 bananas? I'm all confused with Algebra, never took it, so I can't help you with the equations.

That's my guess, haha!

i am not good at equation actually. but i find it hard to imagine how those mathematicians were able to discover those formula that brings the right calculations just to every thing and that is why we are able to build buildings. those old scholars formulated such good math or formula like every thing has its way to find the answer to every math problems. like every thing involves in numbers. algebra makes us see the world in new perspective.

before i tried to calculate math by my mind without expressing or putting it in equation but we have to make an equation for it. math is like a language. sometimes i know what to say but i just can put in words in english cause i am not that fluent in english though i know almost every word in english but to put them in right construction of words are too hard for me many times. and so the same way in math i know how to calculate in my thoughs but to put it in paper is just too difficult for me.

(500-(199+259))/20=2.1

I had to get tutored thru my last year of math in high school - and I've been been out of high school for nearly 40 years!

I don't use algebra because it's complicated for me. I use basic mathematics to solve the basic problems and questions in life. Example would be, what I be the formula for a successful saving of money? I use the expression: Income - Savings= Expenses. Algebra teachers will recommend this formula: Income - Expenses= savings. This doesn't work often. I hope that the other responders have given you the right answers to your questions.
