To determine the winner, we need to calculate the time it takes for each car to complete the 100-mile race.
For Car A: Speed = 10 miles per hour Distance = 100 miles Time = Distance / Speed = 100 miles / 10 miles per hour = 10 hours
For Car B: Speed = 5 miles per hour Distance = 100 miles Time = Distance / Speed = 100 miles / 5 miles per hour = 20 hours
However, Car B has a 10-hour headstart, so we need to subtract that from its total time: Adjusted Time for Car B = 20 hours - 10 hours = 10 hours
Both cars take 10 hours to complete the race, so they tie.

Most Western observers want Ukraine to rid itself of nuclear weapons as quickly as possible. In this view, articulated recently by President Bill Clinton, Europe would be more stable if Russia were to become "the only nuclear-armed successor state to the Soviet Union." The United States and its European allies have been pressing Ukraine to transfer all of the nuclear weapons on its territory to the Russians, who naturally think this is an excellent idea.
President Clinton is wrong. The conventional wisdom about Ukraine's nuclear weapons is wrong. In fact, as soon as it declared independence, Ukraine should have been quietly encouraged to fashion its own nuclear deterrent. Even now, pressing Ukraine to become a nonnuclear state is a mistake.
A nuclear Ukraine makes sense for two reasons. First, it is imperative to maintain peace between Russia and Ukraine. That means ensuring that the Russians, who have a history of bad relations with Ukraine, do not move to reconquer it. Ukraine cannot defend itself against a nuclear-armed Russia with conventional weapons, and no state, including the United States, is going to extend to it a meaningful security guarantee. Ukrainian nuclear weapons are the only reliable deterrent to Russian aggression. If the U.S. aim is to enhance stability in Europe, the case against a nuclear-armed Ukraine is unpersuasive.
[1]But, he does give Putin a pass on the invasion itself. Couldn't Putin have won the desired concessions with just sabre-rattling and having a skirmish on the border instead of a full on invasion, which is slowly destroying both Ukraine and Russia.

Something like: ------
class MathOps{
public MathOps(RoundingMode mode, int scale) {
this.mode = mode;
this.scale = scale;
}
....
public BigDecimal add(BigDecimal x, BigDecimal y){
return x.add(y).setScale(scale, roundingMode);
}
....
public BigDecimal divide(BigDecimal num, BigDecimal denom) {
return num.divide(denom, scale, roundingMode).setScale(scale, roundingMode);
}
...
}
-----
You can then either create a new instance when you need to perform a math operation or just create a singleton instance if scale and rounding mode are always the same.For financial calculations in US, I would recommend using RoundingMode.HALF_EVEN. From the docs "Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for RoundingMode.HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for RoundingMode.HALF_DOWN if it's even. Note that this is the rounding mode that statistically minimizes cumulative error when applied repeatedly over a sequence of calculations. It is sometimes known as "Banker's rounding," and is chiefly used in the USA. "
