26 X √25 + 15 - 80% of 120 = ?2
(15 × 16) + 242= ? × 16
89 ÷ 512 × (1/64) = (23)?
120% of 25 + 80 X 2 = ?2 - 6
1404 ÷ 26 x 3 + 7 = ?2
(23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
7, 8, 12, 21, 37, ?
500% of (121.8 + 16.4 – 28.2) = ? × 2
Determine the simplified value of the expression: 12 × 15 - 20 + 15 + 12 - 18 + 3 × 4 + 18.
22% of 280 + 34% of 1080 × 5/12 =? + 16% of 460
