Maria buys a one liter soda bottle she accidentally drops the soda bottle and spills 437 millimeters of soda how many soda is left

If you really mean millimeters (which is a measurement) there is 1,000,000 millimeters in a liter. 437 millimeters subtracted from 1,000,000 is 999,563 millimeters left.
If you mean milliliters there is 1,000 milliliters in one liter. So 437 subtracted from 1,000 is 563 milliliters left.

There is 563 milliliters left

hope tis helps
