They are only long if you do them as set out. they all have patterns enabling quicker calculation. For example #1 is 21x10. That is there 10 pairs each adding to 21. It has taken me 10x to explain as to do.

Worked with the pattern on the 4th question. I had the right answer if I didn't include a 6th number 18. We didn't have the correct answer available had I included another 18 as written.

Yes question #4 the answer is 743 with there being 6 #18s. The author only added 5 #18s. Which is the pattern of all the numbers repeating 5x. Seems like the author added them correctly but typed 6 #18s.
