It is difficult within parliamentary rules to use words that properly describe the answers that we are receiving. We are dealing with figures running into enormous sums of money; we are dealing with one item that is equal to almost half the total amount that this parliament is called upon to vote during the current year. Here we have a figure of $329 million, which is a deduction from the over-all total. Obviously that must be computed by some process of arithmetic. Any child at school would be expected, when he was arriving at some total figure, to be able to explain the process by which he arrived at that figure, and I do not think that the Minister of National Defence who is asking this house for the approval of a figure of $1,490,000,000 on this particular item should ask us to accept these figures unless he can at least give us the simple arithmetical process by which the figure of $329 million is arrived at.
