Booster maths worksheet 3

using2.pngSome more examples of the type of arithmetic questions that come up in the SATs. An interesting example is the question which asks to put the digits 7, 3 and 4 into the boxes to make the total of 41.

Sometimes there is more than one way to do this type of question and it is a matter of using ‘trial and improvement’ to solve it.

One good way to tackle it is to look at the units (in this case 1) and see which two digits added together will put a 1 in the units. The only option here is is to add the digits 7 and 4 (which make 11), put these in the units boxes and it is easy from there on.
