Which evaluation metric is commonly used in machine

192.251 + 326.233 + 125.021 + 19.273 = ?

300% of (3341 – 471) = ? × (√4225/195)

? × 5.5 = √1225 + 40% of 30% of 37.5% of 5000 – 6³

What will come in the place of question mark (?) in the given expression?

√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?

2350 – 4830 + 9570 + 3350 – 1720 = ?

What will come in the place of question mark (?) in the given expression?

(96 - 59) X 6 + ?² = 136.5 X 4

What will come in the place of question mark (?) in the given expression? 

(240% of 175 ÷ √16) X 6 + 80% of 400 = ?³ + 179 + 42
