 As discussed above, the amount of ETH issued in a given day is dependent upon the total ETH staked. At time of writing, this is approximately 1700 ETH/day.
 
-To determine the average gas price required to completely offset this issuance in a given 24-hour period, we'll start by calculating the total number of blocks in a day:
+To determine the average gas price required to completely offset this issuance in a given 24-hour period, we'll start by calculating the total number of blocks in a day, given a block time of 12 seconds:
 
-- `1 block / 12 seconds = 5 blocks/minute`
-- `(5 blocks/minute) * (60 minutes/hour) * (24 hours/day) = 7200 blocks/day`
+- `(1 block / 12 seconds) * (60 seconds/minute) = 5 blocks/minute`
+- `(5 blocks/minute) * (60 minutes/hour) = 300 blocks/hour`
+- `(300 blocks/hour) * (24 hours/day) = 7200 blocks/day`
 
 Each block targets `15x10^6 gas/block` ([more on gas](/developers/docs/gas/)). Using this, we can solve for the average gas price (in units of gwei/gas) required to offset issuance, given a total daily ETH issuance of 1700 ETH:
 
-- `7200 blocks/day * 15x10^6 gas/block * Y gwei/gas * 1 ETH/ 10^9 gwei = 1700 ETH/day`
+- `7200 blocks/day * 15x10^6 gas/block * `**`Y gwei/gas`**` * 1 ETH/ 10^9 gwei = 1700 ETH/day`
 
 Solving for `Y`:
 
-- `Y = (1700(10^9))/(7200 * 15(10^6)) = (1700(10^3)/(7200 * 15)) = 16 gwei` (rounding to only two significant digits)
+- `Y = (1700(10^9))/(7200 * 15(10^6)) = (17x10^3)/(72 * 15) = 16 gwei` (rounding to only two significant digits)
 
 Another way to rearrange this last step would be to replace `1700` with a variable `X` that represents the daily ETH issuance, and to simplify the rest to:
