i PLEASE NEED HELP WITH 4010 base five minus 1234 base 5!! please and thank you I know that the numbers add to more than five so they need to be different
I'd just use the usual method taught in schools, 'borrowing', but it's a little difficult to illustrate on here.
Instead you could use 'equal addition' as follows.
4010-1234
adding 1 to both numbers
=4011-1240
adding 10 to both numbers
=4021-1300
adding 200 to both numbers
=4221-2000
=2221
It's rather less efficient though.
Hello, cathyharris4!
Have you never ever done a subtraction in other bases?
In C4, we can't subtract 4 from 0, so we "borrow" from C3.
The "1" we borrowed represents "5", so we have:
Subtract in C4 and we have:
In C3, we can't subtract 3 from 0, so we "borrow" from C2.
But C2 has "0"; we can't borrow.
So we must borrow from C1.
Now we can borrow from C2:
And we can complete the subtraction:
