@Sheena2907 i think + before - is good practice because it'll reduce potential pupil's errors in evaluations ... don't want them straying below zero if they can help it ... and divide before multiply perhaps originates from ... say you're finding of ¾ a value youd divide by 4 then times by 3

@RachelRileyRR instantly knew 572 is divisible by 11
891, 385, 462, 253 also are
Prove 3-digit integer abc is divisible by 11 if b=a+c
the integer's value is
100a+10b+c
100a + 10(a+c) + c
100a + 10a + 10c + c
110a + 11c
11(10a + c)
hence 3-digit integer abc is divisible by 11
