You first multiply 6 by 13 giving you 78. Then subtract 9 giving you 69. Then subtract 6*6 which is 36 giving you 33. Then you subtract 9 to get 24.
(6 x 13) - (6 x 9) = 78 - 54 = 24
8 plus 1 , minus 5, plus 7 + 13
Apart from itself and 1, the only numbers that divide evenly into 221 are 13 and 17. Therefore, 221 = 13 x 17.
4! - 44/4 = 24 - 11 = 13

I can find 13 ways, not just 7, to make 60 from adding numbers in the 4, 5 and 9 times tables.
2 3 5 7 11 13 17 19 23 29
There is only one number that equals 13. That number is . . . . . 13.
Easy! You do 1, 3, 5, 7, 9, 11, 13 etc.
There are a few options for listing five prime numbers using the digits zero to nine only once:2, 3, 5, 7, 8649012, 5, 13, 647, 809
Nothing goes into 13 equally. No 2 whole numbers multiplied together can make it. Only 6+7=13.
no whole numbers can be multipled to get 13 besides 13 and 1 because 13 is a prime number which means it has no factors beside 1 and itselfhowever, u can multiply using decimals to get 13 such as 6.5*2 and etc.
