After interchanging the given two numbers (not digits), what will be the value of the given equation? 7 and 6 \(4 \times 7 + 6 - 9 \div 3 = ?\)
28
The instruction is to interchange the two whole numbers 7 and 6 (not their digits) wherever they appear, and only then evaluate.
Starting from \(4 \times 7 + 6 - 9 \div 3\), swapping 7 and 6 turns it into \(4 \times 6 + 7 - 9 \div 3\).
Now apply BODMAS, handling division and multiplication before addition and subtraction.
Division first: \(9 \div 3 = 3\).
Multiplication next: \(4 \times 6 = 24\).
Substituting these back gives \(24 + 7 - 3\).
Finishing the addition and subtraction left to right: \(24 + 7 - 3 = 28\).
Hence the value of the equation is 28.

Select the correct combination of mathematical signs to replace (*) signs sequentially and to balance the given equation.
\(64 * 16 * 34 * 8 * 3 = 14\)
Select the set, from the given options, in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
