3rd grade math - arrays
posted by Trevor on .
Mary says that the greater number of counters, the greater the number of different arrays you can form. Give an example that shows that Mary is wrong.
it really doesnt matter as long as you havae a good supply of numbers
is 5 rows of 4 greater than 4 rows of 5
11 > 10.
But 11 can be only
1x11 or 11x1 matrix (array)
But 10 can be
2x5, 5x2, 10x1, 1x10..
so mary is wrong to say....
same goes with any Prime number as it can be only 2 ways to sent that count in an array.
