In algebra
Addition is written as a + b
Subtraction as a -b
Multiplication as 'ab' (Note there is no 'X' symbol, as the 'x' may be confused with the uknown 'x'.
Division as a/b ( like a fracgtion).
13y-6
y = 6 * ( x + 11)
42 divided by 7 is 6. 7y = 42 Divide both sides by 7. y = 6.
abs(y^3 - 4) < 8*y
x + y = 19, so x = 19 - y; xy = 78; Substituting gives 19y - y2 = 78 ie y2 - 19y + 78 = 0. This factorises as (y - 13)(y - 6) so the smaller number is 6 and the other is 13.
