You will always need it for tests and such. For everyday you memorize the important stuff. If you are in school i doubt you can get around it, talk to the teacher for suggestionsHey guys, I suck at algebra. How important is it? Is there a way around it?

I would not give up learning the trade because of algebra.

A x 24 = 48 what is A=? hahahaha

You need to learn trigonometry for electrical theory and that’s easy to learn.

Sorry, but saying you suck at math means you have given up on yourself. That’s not cool.

Are you working in the union or are you working for a ma and pa shopHey guys, I suck at algebra. How important is it? Is there a way around it?

For example, how many 100 watt light fixtures can I put on a 20 amp circuit?

Another example: I give you a water heater element. It has the markings: 1500W 480 VAC. Using your ohmmeter, tell me if the resistance reading is correct.

I think its a non union job. Commercial and residential construction.Are you working in the union or are you working for a ma and pa shop

You have five dollars. Doughnuts cost $1.25 each. How many doughnuts can you buy?

I do a considerable amount of design work as well as installation and my lack of algebraic knowledge hasn't hurt me though I do use geometry at times, especially bending pipe.

Algebra needs to be defined though, is it something like 2+5=X or is it more like 2(50÷1.73)-22.5(13.33X37.348)+18.973Z÷1.414 solve for Z.

If it's the former, every one of us uses it all the time but there's no need to understand the latter.

You must be a good electrishun. 😊

You need an equal sign in your second equation.

But what algebra is, is discovering the answer when an equation has an unknown variable.

How many donuts can I afford today? They're $1.25 each and I have $5.00. The unknown is the number of donuts.

Solved algebraically that's 1.25X = 5.

Isolate the X using the rule that says we can do anything we want to one side of an equation as long as we do it to both sides of the equation, so we set it up as 1.25X/1.25 = 5/1.25

Cancel the 1.25's on the left side (because 1.25/1.25 = 1) so we have X = 5/1.25

5/1.25 = 4.

You can buy 4 donuts.

Written out it would be easier to understand then when typed.

It's easier to see how the fractions cancel.

Right. Only a rudimentary understanding of algebra is needed. We don't need to get into complex numbers and Fourier transforms.
