Say whether the expression will be odd or even.
`5xx778xx3xx4+1`

Answer

To determine whether the expression \( 5 \times 778 \times 3 \times 4 + 1 \) is odd or even, we can follow these steps:

### Step 1: Calculate the product
First, we need to calculate the product \( 5 \times 778 \times 3 \times 4 \).

\[ 5 \times 778 = 3890 \]

\[ 3890 \times 3 = 11670 \]

\[ 11670 \times 4 = 46680 \]

### Step 2: Add 1 to the product
Next, we add 1 to the result from Step 1.

\[ 46680 + 1 = 46681 \]

### Step 3: Determine if the result is odd or even
Now, we need to check if \( 46681 \) is odd or even. An even number is divisible by 2 with no remainder, while an odd number has a remainder of 1 when divided by 2.

\[ 46681 \div 2 = 23340 \text{ remainder } 1 \]

Since there is a remainder of 1, \( 46681 \) is an odd number.

### Conclusion
Thus, the expression \( 5 \times 778 \times 3 \times 4 + 1 \) is **odd**.
