This is supposed to be a math blog??? FAIL. Check your calendar again … This was July’s calendar in 1977, 1983, 1988, 1994, 2005 and 2011. NOT 2012. This year, July begins on Sunday!

Nice spotting and reminds me of the Maths textbook author who used to say that errors in the answers were put there deliberately to elicit such a response as this one. Alas, mine was an oversight from a forwarded email! Thanks for pointing this out for out readers!!

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
