It is 21/10 minus 1/10 = 20/10 or 2
10-4 means the same as 1/104 or in other words 1/10000 = 0.0001
10 - 9 = 1
1/2 minus 1/5 = 3/10
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.

A tolerance of 10% means that the component's "size" will be within plus or minus 10% of its stated "size". A tolerance of 1% means that the component's "size" will be within plus or minus 1%
1 - 10 = -9
2/5 = 4/10 minus 1/10 is 3/10
10% - 1% = 9%
10 - 9 = 1
