Which type of analysis examines historical data to

120% of 250 + 110 + 135 ÷ 5 = ?

2222 ÷ 22 + 992 ÷ 16 + 650 ÷ 25 = ?

721 +21 x 9 - 118 = ? + 82

139 + 323 – √169 + ? = 450

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

16 X ? + 750 ÷ 3 = 60 X 9 + 110

What value should come in the place of (?) in the following questions?

16² – 12 * 20 = 6 * ? - ³√8000

1365 ÷ 15 + (? ÷ 5) = 6² × 3.5

2 X 25 + (30% of 80) ÷ (10% of 120) = ?

Find the simplified value of the following expression:

14.25 × 32 – 11.4 × 15 + 8 – 712 ÷ 8 + 34.15 × 20 – 27 × 21 = ?
