Assessing negative exponents on your calculator
With your issues, you will need to raise figures to powers that are negative. Many calculators have split switch for negating a number that is distinct from the subtraction switch. Some calculators label this (-) , some with +/- . The key is generally close to the = key or even the decimal point.

Then usually you hit the (-) key after a number to negate it, so youвЂ™d hit: 1.005 yx 240 (-) = if your calculator only shows one value at a time,

A donor provides $100,000 up to a college, and specifies it is to be used to provide scholarships that are annual the following twenty years. Each year if the university can earn 4% interest, how much can they give in scholarships?
r = 0.04 4% yearly price
k = 1 since weвЂ™re doing yearly scholarships
P0 = 100,000 weвЂ™re you start with $100,000
Re re re Solving for d gives $7,358.18 Each that they can give in scholarships year.
