I'm not sure what would be a trick for the number 3. I will presume you would mean the way to tell if a number is a multiple of 3. A number is a multiple of 3 if the sum of its digits is also a multiple of 3. For example 585 is a multiple of 3 since' 5+8+5 = 18 which is a multiple of 3. The number 47 is not a multiple of 3 because 4+7 equals 11 and that is not a multiple of 3. There is a second digit that has a similar rule for multiplicity. That digit is 9, which just happens to equal 32 . In fact, since 18 is a multiple of 9, 585 must be a multiple of 9 also.

Which is furthest on the number line from negative 4 positive 3 or negative 10?
Its a trick question they are equal
Is 999 in the 3 times tabel?
Yes, it is. If you go far enough you'd get to 333x3 = 999. The trick to find out if a number is in the 3 times table is simply dividing by 3 and see if you end up with the number zero in the end.
Is 524 divisibility by 3?
no.. heres a trick: if you add together the numbers (5+2+4) and that answer equals a number that is divisible by 3 then the number is divisible by three 5+2+4=11 11 is not divisible by 3 therefore, 524 is not divisible by 3
What is the trick of knowing that a number is divisible by three?
add the numbers up, then if it comes out to a multiple of 3, it is divisible Divide the number by 3, and if the answer is not a whole number, it is not divisible. For instance, 1047 is divisible by 3. while 1045 would be impossible since it is a difference of only 2 from 1047.
Which is the smaller number 028 or 08?
Assuming this is not a trick question, 8 is the smaller number.
