The symbols used are: [tex]1 \times 2 \times 3 - 4 = 2[/tex] or 1 + 2 + 3 - 4 = 2
Given that we have to use symbols to get the answer
1 2 3 4 = 2
We can use basic arithmetic operations to get the answer
The basic arithmetic operations are addition, subtraction, multiplication and division
Addition is usually signified by the plus symbol "+"
Subtraction is denoted by symbol " - "
Multiplication is usually signified by the symbol "x"
Division is denoted by [tex]\div[/tex]
So we can use these set of symbols and make the equation true
Given is: 1 2 3 4 = 2
Multiplying 1 and 2 and 3 will give 6. When 4 is subtracted from 6 we get 2. This makes the statement true
[tex]1 \times 2 \times 3 - 4 = 2\\\\6 - 4 = 2\\\\2 = 2[/tex]
Thus the given equation has become true
Therefore the symbols used are: [tex]1 \times 2 \times 3 - 4 = 2[/tex]
