In Ohm’s Law, E = I x R, where E is energy in watts, I is current in amperes, and R is resistance in ohms. Very scary sounding, right?
Here’s the question: if energy (E) is 12 watts, current (I) is 4 amperes, what is the resistance (R) in ohms?
You plug in the values given, and you get 12 = 4 x R. We won’t insult your intelligence by providing the rest of the answer. We will only note that the entire question comes down to: WHAT TIMES 4 IS 12?
What’s challenging about the math on the SAT and ACT is not the math itself. In fact, the math is extremely simple. Shockingly simple, in fact. After all, it’s elementary level, not high school.
What IS challenging about the math is the READING involved.
You have to READ and UNDERSTAND the questions. THAT often is much harder than the math itself.
How many times have you read a math question and thought:
“What the $%&*@ are they asking??”
The more you learn about the math sections on the SAT and the ACT the more you realize they are really more READING tests than math tests!
