1. Number added or deleted






2. The number of ways independent events can occur together.






3. In general - difficult questions require how many steps to solve?






4. gcd(m,n)*lcm(m,n)

18. How many liters of a solution that is 10% alcohol by volume must be added to 2 liters of a solution that is 50% alcohol by volume to create a solution that is 15% alcohol by volume?






19. Sq. rt(2)






20. In general - medium questions require how many steps to solve?






21. 45-45-90 triangle basic lengths of sides






22. Simple probability






23. Compound interest rule






24. Formula for area of a Trapezoid

42. Compound interest formula






43. Think of averages as what? The average of 3 - 4 - 5 - and x is 5. What is x? 3 is 2 less than 5 4 is 1 less than 5 - 5 is the average - x = 5 + 3 = 8
