A markup calculator is used to work out the final retail cost of an item if you know the price it was bought for and the percentage markup (how much profit) you want to make. There are online calculators which can do this automatically for you, or you can just use a normal calculator: for example, if you buy something for 100 and want to make 20% profit, the final price should be 100*1.2 = 120.

222500.00 × 20% = 44500 Note: without a calculator: 222500.00 x 20 = 4450000 then place the decimal point two places to the left, thus 44500.00
To calculate (20^{20}) without a calculator, you can use the properties of exponents. First, express 20 as (2 \times 10), so (20^{20} = (2 \times 10)^{20} = 2^{20} \times 10^{20}). Then calculate (2^{20}) and (10^{20}) separately: (10^{20} = 1) followed by 20 zeros, while (2^{20} = 1,048,576). Finally, combine these results: (20^{20} = 1,048,576 \times 10^{20}), or (1,048,576) followed by 20 zeros.
