thx so much everyone
What is 0 x 1 + 1 x 1?

In terms of Boolean Algebra, and can you please show how you did it? Did you go from left to right or do multiplication first? Thanks!

I think:(0 x 1) + (1 x 1)
= 1

Always do multiplication first.
(0 X 1) + (1 X 1)
0 + 1
1
Hope this helps.
(0 X 1) + (1 X 1)
0 + 1
1
Hope this helps.

Always do multiplication first.
0 x 1 + 1 x 1
= (0 X 1) + (1 X 1)
= 0 + 1
= 1
0 x 1 + 1 x 1
= (0 X 1) + (1 X 1)
= 0 + 1
= 1

The order of operations: parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank).
0 x 1 + 1 x 1
= 0 + 1
= 1
0 x 1 + 1 x 1
= 0 + 1
= 1

When you use x for "and" and + for "or" it works the same as arithmetic modulo 2, and the order of operations are the same then also.
It should be read as (0 x 1) + (1 x 1) = 0 + 1 = 1.
Be careful not to get confused with exclusive or: x⊕y
I had to check the reference to make sure I was reading the symbols right. The reference covers the properties of multiplication and addition. It doesn't cover parentheses, but I'm sure mathematicians and engineers are not so silly as to use the opposite convention.

0 x 1 = 0
1 x 1 = 1
0 x 1 + 1 x 1= 0 + 1 = 1
so the final answer is 1
1 x 1 = 1
0 x 1 + 1 x 1= 0 + 1 = 1
so the final answer is 1

1 0x1+1X 1= 0+1= 1

Multiplication always takes precedence over addition or subtraction.
Therefore the answer is 1
Therefore the answer is 1
2011-01-25 3:40 pm
Answer is the same either way. 0x1 =0 + 1x1=1 or 0x1=0+1=1x1=1
