38 x 43 = 1634 which in Roman numerals is MDCXXXIIII Multiplying XXXXIII (43) by XXXVIII (38) in Roman numerals: XXXXIII*XXXVIII = XXX(XXXX+III)+VIII(XXXX+III) Multiplying out the brackets = MCC+LXXXX+CCCXX+XXIIII Total sum of numerals = MDCXXXIIII (1634) By separating the numerals into tens and units makes multiplication a lot easier. In a way this is what we do today when tackling long multiplication.
How about: 8*9 = 72
1 x 76, 2 x 38, 4 x 19.
The property illustrated by the expressions (46 \times 38) and (38 \times 46) is the commutative property of multiplication. This property states that changing the order of the factors does not change the product; thus, (46 \times 38) equals (38 \times 46). Both expressions will yield the same result when calculated.
1 x 38, 2 x 19.
The number 38 can be obtained through multiplication by various combinations of factors. For example, 2 multiplied by 19 equals 38, as does 1 multiplied by 38. In mathematical terms, 38 is a composite number that can be expressed as the product of its prime factors, which are 2 and 19.
As a product of its prime factors: 2*19 = 38
38 is an even number so it is divisible by 2. 38 = 2*19 19 is a prime so there are no further factors.
With whole posieive numbers, there are two. 1 x 38 and 2 x 19.

You multiply it and your finding space of what it has. The multiplication makes the squared.
