### Math is about solving problems!

July18

There is a dilemma in Mathematics – the pressure to get students through coursework versus the joy of problem-solving and mathematical investigation. As sure as one plus one equals two, it happens year after year. Kids who have been bringing home A’s in chemistry and acing AP Calculus arrive at college with visions of STEM […]

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)?]
