+%This is a script to answer Problem 1 for Project Euler
+%What is the sum of all the multiples of 3 or 5 that are less than 1000
+
+%Setup your variables
+fullSum = 0;	%To hold the sum of all the numbers
+numbers = 0;	%To hold all of the numbers
+counter = 0;	%The number. It must stay below 1000
+
+while(counter < 1000)
+	%See if the number is a multiple of 3
+	if(mod(counter, 3) == 0)
+		numbers(end + 1) = counter;
+	%See if the number is a multiple of 5
+	elseif(mod(counter, 5) == 0)
+		numbers(end + 1) = counter;
+	end
+
+	%Increment the number
+	++counter;
+end
+%When done this way it removes the possibility of duplicate numbers

+fullSum = sum(numbers);
