Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.

56 * 492 * 6 * 7 * 123 = 507

Select the correct combination of mathematical signs that can sequentially replace ‘*’ sign and balance the equation given below.

If 'A' stands for '-', 'B' stands for '×', 'C' stands for '+', and 'D' stands for '÷', then what is the value of the following expression.

What will be the value of expression if the signs ‘(-)’ and ‘(+)’ are interchanged?

75 + 42 – 6 × 56 ÷ 7 + 6 × 3 – 2

What will be the value of the given expression after the following interchanges?

Expression: 84 ÷ 11 - 15 X 14 + 75

If ‘ × ’ means ‘ + ’. ‘+’ means ‘÷’, ‘-’ means ‘×’ and ‘÷’ means ‘-’, then 9 × 8 – 5 + 40 ÷ 3 = (?)

Which two signs need to be interchanged to make the following equation correct?

62 – 14 × 75 ÷ 15 + 50 = 82
