If it takes that long to explain a math equation, do they only learn about 4 equations per class. Friggin insane.
Yes...that's an easy one to do in your head...35 x 10= 350...then take 35 x 2=70...350+70=420. That's just how I do stuff like that in my head...
Heck, I'm betting it would take her students about 20 minutes to calculate my blood pressure right now.
Right?! Its not faster...its not simpler...whats the point?! No wonder we are falling behind other countries in academics! Da goobermint had to have a hand in this...it just reeks of bureaucrats!
I had the answer in less than 5 seconds. Seems pretty convoluted, but I no longer even remember how I was taught to do that. That's how I did it.
I didn't count, but yeah, not much of a problem. Now 15,025 x 325 gonna take me some time and paper. The grey matter isn't what it was.
I gots a calculator on the phone and computer that handles the heavy work for me. Mine's even greyer nowadays.
Well, obviously not to be rude, but my father was a math teacher, back in the days of deforestation for the "big paper" companies. But we were not allowed calculators until we could show that we knew the math involved. After all, if you have no clue what the answer should be, how do you know you entered the right numbers?? Garbage in.. garbage out.
I am having trouble putting my thoughts to paper, but here goes. I hope you can follow it. In my case, I am pretty much 100% wood for heating and total electric. My electric bill may very $10 between summer and winter. I used around 4 ½ cords this year. To eliminate a few of the variables, I would convert my total wood usage to BTUs. BTUs are BTUs no matter what the source. Using the FHC BTU/cord chart Firewood BTU & Drying Chart and averaging the BTUs of the species in my pile. I am not considering seasoning time. In my case 4 ½ cords and choosing a median BTU per cord from the chart. 4 ½ cords x 22.5 average of BTU from the chart = BTUs/year 4.5 x 22m BTUs/cord = 4.5 x 22000000= 99000000 BTUs/heating season. Look up the BTUs in your secondary heat source. In my case, 3.413 per kWh of electricity. Now for all practical purposes I am not using any electricity for heat. Total of BTU/cords used/year divided by 3.413. 99000000 BTUs / 3.413 = 29006738 kHw saved. Here is where my example will goes haywire because I don’t know the kWh rate for my electric kWh saved x my kWh rate = $$s saved. You have to factor in the cost of saw and splitter plus, maintenance and fuel. We are going to assume, (and I well know what assume makes) that you are buying your wood. I my area you can buy seasoned??? wood for about $150 to $200/cord. My example 4.5 cords x $200 = $900 at worst case scenario. Cost of your stove, I don’t figure in. Your furnace cost money if you have to replace it or if it was there when you bought your place. Now you have to figure in your time. I am retired and making firewood as a hobby and exercise. I kind of figure if I got a gym membership and had to drive 40 miles round trip, I am ahead making firewood. If I was not making firewood I would be vegetating. Cost of time is up to you. I hope you can follow my logic. I would think this would give you a close idea of savings. I may have some conversions wrong, but that is how I would figure savings.
Just remember to carry the unicorn pooping the rainbow. Then you will be centered and have zero remorse, allowing you to find inner peace, and maybe "X", if you're lucky.
Over the years; I have observed and it has been reinforced; that there are people out there that truly believe that change is good Not change for the sake of betterment, but change for the sake of change alone.
If I had to do math that way I would not do math. No wonder people love calculators if they learn to do math like that...
There also lies another problem. People get so accustomed to having a machine do their figuring, they then forget how to do it in their own gray matter. Just look at business and when a computer don't work, most can not do business because they can't figure out dollars and cents.
