Stake._intrest(uint256) (contracts/stake.sol#94-111) performs a multiplication on the result of a division:
-index_scope_0 = (stake_percent_lvl3[0] - stake_percent_lvl2[0]).mul(100000).div(stake_percent_lvl3[1].div(OneDay) - stake_percent_lvl2[1].div(OneDay)) (contracts/stake.sol#105-107)

Stake._intrest(uint256) (contracts/stake.sol#94-111) performs a multiplication on the result of a division:
-index = (stake_percent_lvl2[0] - stake_percent_lvl1[0]).mul(100000).div(stake_percent_lvl2[1].div(OneDay) - stake_percent_lvl1[1].div(OneDay)) (contracts/stake.sol#99-101)
-extra = (_days - stake_percent_lvl1[1].div(OneDay)) * index (contracts/stake.sol#102)
