It cost... well I'm not sure but I think it is more than $300.00 but again that is a guess.
Multiplication is simply 'complex addition'. Take, for example, the sum 6x7. If you add 7+7+7+7+7+7 you get 42 - which is the same result of multiplying 6x7 3x4 is the same as 3+3+3+3 etc.
6x7=42
6x7 equle = 42
6x7=42 42=5=47 so 6x7+5=47
if you do 3x7 and you need to get 6x7 then just do it 2 times
No.
42
42
6X7=42 BECAUSE YOU HAVE 6 GROUPS OF 7 SO THAT MAKES IT 42
Strewth - 42 (and that was without a calculator)
6x7=42 42+5=47 5 over 6x7=47
6x7=42
