bonjour
5 ³ - 10 ² = 125 - 100 = 25
( 5 ² - 19 ) x ( 2 + 3 )² = ( 25 - 19 ) x 6 ² = 6 x 36 = 216
5 ⁰ - 8 ⁰ / 5 ¹⁰ + 8 ¹⁰ = 1 - 1 / 5 ¹⁰ + 8 ¹⁰ = 0
7 ⁻⁴ x 21 x 14 = 0.12244898
15/25 + 6 x 3 ⁻² = 3/5 + 6/9 = 27/45 + 30/45 = 65/45 = 13/9
5² + 2² x 9 = 25 + 36 = 61
9 / 4 + 4 = 9 /8 = 1.125
5 x 1000 - 2 x 100 = 5 000 - 200 = 4 800
5 - 2 x 36 = 5 - 72 = - 67
2 x ( 30 - 25 ) = 2 x 5 = 10
4 + 6 ² = 4 + 36 = 40
