I am using scratch. I acquire two values from the user and have to find the numbers divisible by 2 & 3 between those values . How can I count those numbers without using arrays ( just by using basic operations) ?

here is the project :

If you're just counting them you don't need to actually find them.

eg for divisible by 2, look at the different combinations (start odd or even, end odd or even) and you should be able to work out how to count the number of even values. Do this with a small range just to get the pattern.

Similarly for divisible by 3. There are now 9 combinations (start mod 3 = 0, 1, 2 and end mod 3 = 0, 1 ,2) but you should still be able to work something out. If the range is 0 mod 3 you can just divide the range by 3 (eg you have range of 27 there are 9 numbers divisible by 3 and it doesn't matter whether it is 1 to 27 or 221 to 247 or whatever).

Not sure you understood the question but certainly no need to necropost.

delete (all) of [numbers divisible]
ask [a?] and wait
set [a] to (answer)
ask [b?] and wait
set [b] to (answer)
set [count] to (a)
repeat until <(count) = (b)>
if <<((count) mod (2)) = [0]> or <((count) mod (3)) = [0]>> then
add (count) to [numbers divisible]
end
change [count] by (1)
end
set [what to say] to []
repeat (length of [numbers divisible] :: list)
set [what to say] to (join ((join(what to say) (item (1 of [numbers divisible] :: list))) [,])
end
say (what to say)

That's to make it say the numbers, but all the numbers would appear in the list.
