Algorithm to get the submultiples of each number in a range

I have this exercise in mind, I keep trying to solve it in Java but I’m not able to create a correct algorithm to get the submultiples of each number in a range, the start and the end of the range is user defined. Besides, the number 1 doesn’t count as a submultiple. For example, in a range between 3

Java Calculator program issue

I am trying to develop a calculator program that inputs an arithmetic expression of the form number operator number = and computes the result of the expression. The expression will be evaluated from left to right not considering regular operator precedence. For example, the expression 14 – 5 * 3 = will produce 27.0. The value = displays the final

Level calculation

somehow I can’t think of a solution to a problem that is actually quite easy. It’s about a level system where I need a kind of formula that is very simple but I can’t think of it. I calculate the level from the experience points and there you need e.g. for level 1 1.000 EXP, for level 2 3.000 EXP,

How to restore initial fraction from a big decimal

I have a list of fractions that have to be converted to a bigDecimal first and then converted to a fraction again. I have made two methods: first converts from fraction to bigDecimal and the second does the opposite. However, I have noticed that during the conversion I am losing on some precision, hence I was wondering if there is

Put sin on segment in 3d

i need to put a sin function, or any other function on start of segment in 3d space. Something like that: Example But in 3d space, help me pls, i spent about 4 days for solving it, but did not get result There are 2 points in space at arbitrary positions. I need a sinusoid between these two arbitrary points.
