Question

If 10-8= 5 / 12-8=8? So find 18-13=?

Answer 1

It will be 11,

Because of since 10-8=5/12-8=8,

The the order for the subtraction is =+2,

So if 10-8=5, then,

it's subtraction rule is 2,

which it becomes 5,

which when 12-8=8,

the order still is subtract from 2,

which is 4,

which when 12-8=8,

the addition rule is +3,

so when 18-13=10.5.

so your answer will be 10.5,

Hope it helps!
