Math – Too Difficult For 6-Year Olds?

Once again, do you think these equations are a tad too difficult for 6-year olds? Do note that the boxes are everywhere in the equations and I think that this is confusing the child coz sometimes they need to subtract and sometimes add in order to get the answer for the box.  I explained the basics/rules to Alycia but I don’t know if she remembers.
