In one of your excersises,"Place value" , it asks you "What is eight thousand four hundred seven in standard in standard form". Firstsly, I believe that should say "and seven". But the main problem is that the acceptable answer formats only allows for integers and fractions, not 8.407 x 10^3. In short , it is not asking for standard form. Well to be honest, after a little bit of reasearch I learned that standard form is the term for x times 10 ^ y, but In British English, which is what I am familiar with. Maybe a less amigious term could be used if this isn't an error after all. :-)
