4) ÷ 4 )bonjour
• 4 + 4 - 4 - 4 = 8 - 8 = 0
• (4 + 4) ÷ (4 + 4) = 8 ÷ 8 = 1
• (4 ÷ 4) + (4 ÷ 4) = 1 + 1 = 2
• (4 + 4 + 4) ÷ 4 = 12 ÷ 4 = 3
• 4 + 4 x (4 - 4) = 4 + 4 x 0 = 4 + 0 = 4
• (4 + 4 x 4) ÷ 4 = (4 + 16) ÷ 4 = 20 ÷ 4 = 5
• 4 + (4 + 4) ÷ 4 = 4 + (8 ÷ 4) = 4 + 2 = 6
• 4 + 4 - (4 ÷ 4) = 8 - 1 = 7
• 4 + 4 + 4 - 4 = 4 + 4 + 0 = 8
• 4 + 4 + (4 ÷ 4) = 8 + 1 = 9
