You’re at a casino; you’ve just won a big bet – what do you do? You might want to shout ‘plus’ and ‘minus’ as you walk towards the cashier to show your excitement. But what do those two words actually mean in betting?

In the same way that ‘plus’ and ‘minus’ start with the same numerical values but have completely different meanings, in betting ‘plus’ and ‘minus’ can mean completely different things. That’s what makes it such a fascinating game to try and understand fully. Let’s take a closer look at what exactly those two words mean in relation to betting.

## The Math Behind The Math

‘Plus’ and ‘minus’ start with the same numerical values but have completely different meanings. In statistics, it is common practice to denote the plus and minus signs in front of a number as superscripts to represent a deviation of that number from the average. For example, the number 36.8 represents a deviation of +0.8 degrees from the average temperature of a daily average temperature in Singapore.

In the same way, when you play the game of roulette you will encounter the term ‘blue chip’ to denote a winning bet. The number of blue chips that you will encounter is dependent on how much you wager. If you wager $1, it is very likely that you will see 1 blue chip in return. However, if you wager $100, it is highly likely that you will see 100 blue chips in return because the mathematical odds are in your favour. This is why it is a good idea to use superscripts and deviate from the average when denoting big wins and losses in relation to the game of casino. This will provide you with a clearer picture of how the numbers work behind the scenes, and allow you to better understand how your wins and losses stack up against the house’s overall average.

## What Is A Big Bang?

In the game of casino, when a player wins a big bet they will often say ‘that’s a big bang!’ The expression refers to the fact that the player just won a large sum of money and is unlikely to see that amount returned immediately. It is similar to the expression ‘that’s a once-in-a-lifetime opportunity!’ which people use when they score a hit in a game of golf, or a goal in a sport such as football. However, in casino the expression is used to refer to a big win because the odds are often heavily against the player. In most casinos you will see that the house edge is between 5% and 15% on large wagers, so even a small win can be considered a big win in comparison. That’s because the house edge takes into consideration all the rules and regulations that govern the game. For example, in blackjack, the house edge for each successive deck is 1.4%. If you wager $1, you will get $1.40 back on average. However, if you wager $100, you will lose 79.6% of your money on average – because the mathematical odds are against you.

## When Does A Big Bang Occur?

In the game of casino, a big bang occurs whenever a player wins a large sum of money. Even if the player loses, if they break even or win just a little they will often say ‘that’s a big bang!’ In relation to blackjack, a big bang can occur when a player wins 21, and in relation to let’s say, roulette a big bang can occur when a player bets $100 and wins $1000 immediately. These are some pretty big numbers! In these cases, the house edge is considered to be at its lowest because the mathematical calculations are in the player’s favour. That being said, the average big bang in casino is only seen with high roller tables where the maximum bet is $10,000 or more.

## Can I Have A Big Bang When I Lose?

The answer is yes! In fact, many casinos encourage their players to have a ‘banging loss’ whenever they lose a large sum of money because of the large returns that it generates. For example, if you wager $100 and lose, you will have a big banging loss! When that happens, the casino will pay you back your $100 and give you an additional $100 for free. This is why many casinos will give you double or even triple credit cards when you have a big loss because they know that you will be back soon for more!

‘Plus’ and ‘minus’ are two extremely useful and versatile symbols that are used in all sorts of different ways in maths and science. In casino, they are used to denote deviations from the average, and in maths they are used to denote the actual addition or subtraction of two numbers. As you might expect, ‘plus’ and ‘minus’ can be used in reverse to denote the subtraction or addition of something from a larger number. For example, if you want to find the average weight of visitors to a certain website, you would weigh each visitor who comes to the site and then add up all the weights to find the average. The same principle applies in reverse; if you want to find the weight of each visitor to the site you would use the ‘minus’ symbol to denote subtraction and then add up all the weights (minus the weights of those who have already been weighed). Another use of ‘plus’ and ‘minus’ in casino is to show a gain or loss on a card or in a display at the end of a shift. For example, if you won $2,000 in a game of roulette you would put a ‘$2,000 plus’ sign in front of that number to indicate that you won a grand total of $2,000. At the end of the night, if you lose $500 you would put a ‘$500 minus’ sign in front of that number to show that you lost $500 and not $2,000 as you first thought. The casino can do this because they keep a running total at the end of every shift, so they always know how much each player has won or lost. And last but not least, if someone wins $5,000 at one table and then wanders over to another table to continue playing, they might say ‘that’s a $5,000 plus!’ because they are essentially referring to the same amount of money in a different way. ‘Plus’ and ‘minus’ can also be used to show a gain or loss in scientific calculators and computers.
