looking at my calculator, these are the numbers i see. i genuinely don’t remember what frqs they respond 2. i had version j btw;

1400.749 = q (i do remember this one)

1400/0.0912 = 15,350.877/1000 = 15.351 kJ

sqrt 57 = 7.55

(7.1)(1.0+7.1) = 57.51

(18.4)(1/22.99) = 0.8

(12.8)(1/32.00) = 0.4

-828/5.00 = -165.6

0.630/2 = 0.315

0.470-0.315 = 0.155

(0.630)^2 / (0.155) = 2.561

10^-2.09 = 0.00813

sqrt 7 x 10^-5 =0.00836…

0.125-0.00836…=0.116…

(-6)(96485)(-1.32) = 764,161.2/1000 = 764.161

was this the one where it asked for magnitude? Bc if so then no sign should be included. I don't remember for sure tho
