What sign, in place of \( \square \), will make the equation true?

\[ \large 6 \square 2 = 4\]

Using only \( + \) and \(- \), can we fill in the boxes to make the following expression true:

\[ \large 6 \square 4 \square 2 = 8 ?\]

Out of the 4 standard arithmetic operations (\(+, - , \times, \div\)), can we place them into \( \square \) such that the equation is true?

\[ \large 1 \square 2 \square 3 = 6 \]

Note: Each \( \square \) could use the same or a different operation.

Using only \( + \) and \(- \), can we fill in the boxes to make the following expression true:

\[ \large 1 \square 2 \square 3 \square 4 \square 5 = 10 ?\]

Out of the 4 signs (\( +, -, \times, \div\)), how many of them could be placed in \( \square \) to make the statement true?
