if 'g' = minus 3 then 20 + -3 = 17 17 + -3 = 14
-7
20 minus 17 minus 3 minus 2 equals -2
18
27 times 3 minus 46 plus 23 equals 58.
y equals 3
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.
10x3+8=80-60+? 30+8=20+? 38=20+? 38-20=? 18=? The answer is 18.
3 + 6 - 2 + 14 - 3 + 2 = 20
20 + 15 - 3 = 32
20
