Stepping down from an advanced calculator

Click For Summary
SUMMARY

The discussion centers on transitioning from advanced graphing calculators to simpler models, specifically the CASIO fx-260. Users express challenges in inputting complex equations without utilizing parentheses while ensuring correct order of operations. The recommended approach involves calculating the denominator first, including raising .04 to the power of 4 and multiplying by π, then using the reciprocal function to multiply by the numerator. This method effectively addresses potential order of operations issues inherent in simpler calculators.

PREREQUISITES
  • Understanding of basic arithmetic operations (addition, subtraction, multiplication, division)
  • Familiarity with order of operations (PEMDAS/BODMAS)
  • Knowledge of using scientific calculators, specifically the CASIO fx-260
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Research the functions of the CASIO fx-260 calculator
  • Learn about order of operations in mathematical expressions
  • Explore techniques for simplifying complex equations without parentheses
  • Study the implications of using reciprocal functions in calculations
USEFUL FOR

Students transitioning from advanced calculators to simpler models, educators teaching basic calculator skills, and anyone looking to improve their mathematical input techniques without relying on parentheses.

This is kind of sad, but I'm beginning to realize how much I rely on my graphing calculator any more for solving equations and whatnot. I am trying to incorporate a much simpler calculator from time to time (CASIO fx-260) and am struggling with some very basic operations.

Say I have the equation \tau_A=\frac{5kN\cdot.040}{\frac{\pi}{2}\cdot(.04^4)} and I want to input this without using parenthesis. What is the order to type this in the calculator with?

If you have a calculator that won't track order of operations for you, and I have one that let's you type it out on the screen to confirm it's correct, I would just go with the latter and restrict myself to only using it for basic calculations.

As for your guy, I would start with .04, raise it to the power of 4, multiply by pi, divide by 2, hit the "1/x" key, then multiply by all the stuff in the numerator consecutively. The thing I would be worried about when entering this expression into the calculator is if I try to do divide by, then enter .04, then raise to the 4th power, that it would divide by .04 before raising everything I have so far to the 4th power (some calculators will recognize a Pemdas violation I believe, but some won't).
 
Thanks, following the order you laid out got the correct answer. I hadn't thought of doing the denominator then reciprocating it to multiply by the numerator, but I see it now!
 
Use those bracket buttons, for example, numerator / ( ... ) =

Oh sorry, you said without using parentheses. Odd :).
