When silicon, which has four valence electrons, is doped with gallium, which has three valence electrons, "holes" are created where electrons are missing. These holes can accept electrons, making the material a p-type semiconductor.
√2703.88 × √784.15 – 26² = ? - (34.85)²
119.98% of 80.02 - 15.12 × 2.02 + 19.95 = ?

18.99% of (102.99 + 98.01) + 6.01³ - (9.02 of 2.99) = ? of (64.02 - 28.98)
12, 16, ?, 36, 52, 72
? = 540.24 + 1022.97 – 11.992
999.99 + 99.99 + 99= ?
(9116.89 – 8024.89 + 902.95) × 14 = 1800 × ?
