### What is less then and greater then?

The mathematical symbol for 'less than' is < and for 'greater than' is > On the keyboard, < is found over the comma, while > is found over the period, or full stop. One way to remember which way the symbols go is this: BIGGER > smaller smaller < BIGGER or 2 > 1 (2 is greater than 1) 1 < 2 (1 is less than 2)

### If two dice are rolled what is the probability of getting s sum less than 3?

The only number less than 3 that you can get with two dice is 2. The probability of getting a 2 is 1/36. The only number less than 3 that you can get with two dice is 2. The probability of getting a 2 is 1/36. The only number less than 3 that you can get with two dice is 2. The probability of getting a 2 is 1/36. The only number less than 3…

### What is the largest number that should be added to -3 to get a sum less than -1?

There is no solution if the question asks for 'less than -1'. Suppose a is the largest number. Then we have -3+a<-1, so a<2. But then I can take the number x:=(a+2)/2. This number is still less than 2 (it is in the middle of 2 and a on the number line) and so -3+x<-1. But x>a, which contradicts a being the largest number satisfying the required property. If it's 'less than or equal to…
