Add brackets where appropriate to make the equation true 1+2*3+4*5+6*7+8*9=505 (Note: * "is a multiply sign)

Add brackets where appropriate to make the equation true 1+2*3+4*5+6*7+8*9=505 (Note: * "is a multiply sign)

(1+2*3+4)*5+(6*7+8)*9=505

Add parentheses to the following formula to make the equation true
The formula is: 40 + 50 * 12-8 = 240
40+50*12-8=360
40+50*12-8=1072
40+50*12-8=632

40+50*（12-8）=240
（40+50）*（12-8）=360
（40+50）*12-8=1072
（40+50*12）-8=632

Add, subtract, multiply, divide and bracket in the following formula to make the equation true
1 2 3 4 5 =10 1 2 3 4 5 =10 .

12-3-4+5=10, 1+2+3×4-5=10, (1+2)×3-4+5=10, (1+2)÷3+4+5=10, (1+2+3-4)×5=10
