MetaRush._reflectFee(uint256,uint256) (#914-920) performs a multiplication on the result of a division:
-tFee = tAmount * _reflectionFee / 100 (#915)
-rFee = tFee * currentRate (#916)
MetaRush.burnFeeTransfer(address,uint256,uint256) (#947-955) performs a multiplication on the result of a division:
-tBurnFee = tAmount * _burnFee / 100 (#948)
-rBurnFee = tBurnFee * currentRate (#950)
MetaRush.investingFeeTransfer(address,uint256,uint256) (#957-964) performs a multiplication on the result of a division:
-tInvestingFee = tAmount * _investingFee / 100 (#958)
-rInvestingFee = tInvestingFee * currentRate (#960)
MetaRush.marketingFeeTransfer(address,uint256,uint256) (#966-973) performs a multiplication on the result of a division:
-tMarketingFee = tAmount * _marketingFee / 100 (#967)
-rMarketingFee = tMarketingFee * currentRate (#969)
Consider ordering multiplication before division.
