WebbA product of a single number is just the number: Y1 i=1 a i= a1. I know how to multiply two numbers: Y2 i=1 a i= a1·a2. To multiply n numbers for n>2, I multiply the ﬁrst n− 1 of them (which I assume I already know how to do), then multiply the nth: Yn i=1 a i= nY−1 i=1 a i·a n. 1 Again, I can drop the parentheses and write Yn i=1 a i= a1·a2···· ·a WebbHow to calculate reveral summations.
