The expression provided, $6 + 2 \times +3(\times +1)$, contains some ambiguities due to the use of the plus signs and the multiplication signs. I will assume you intended to simplify the expression involving multiplication.

Let's rewrite the expression clearly:

$6 + 2 \times (+3) \times (+1)$

Now, let's simplify it step by step:

1. Evaluate the multiplication:

$2 \times (+3) = 6$

2. Multiply the result by $+1$ (multiplying by $+1$ leaves the number unchanged):

$6 \times (+1) = 6$

3. Add the result to 6:

$6 + 6 = 12$

So, the simplified value of the expression is:

$\boxed{12}$
