How do you distribute imaginary numbers?
Step 1: Distribute (or FOIL) using only the first two complex numbers. Step 2: Simplify the powers of i, specifically remember that i2 = –1. Step 3: Combine like terms, that is, combine real numbers with real numbers and imaginary numbers with imaginary numbers. Step 4: Distribute (or FOIL) to remove the parenthesis.
Why is 1 called the multiplicative identity?
The property states that when a number is multiplied by the number 1 (one), the product will be the number itself. This property is applied when numbers are multiplied by 1. Here, 1 is known as the multiplicative identity element because when we multiply any number with 1, the obtained result will be the same number.
Can a weapon have more than one special ability?
A single weapon cannot have a modified bonus (enhancement bonus plus special ability bonus equivalents) higher than +10. A weapon with a special ability must have at least a +1 enhancement bonus. A weapon or a kind of ammunition may be made of an unusual material.
What’s the limit for rerolling a special ability?
Reroll if you get a duplicate special ability, an ability incompatible with an ability that you’ve already rolled, or if the extra ability puts you over the +10 limit. A weapon’s enhancement bonus and special ability bonus equivalents can’t total more than +10.
How is the price of a magic item determined?
Prices presented in the magic item descriptions (the gold piece value following the item’s caster level) are the market value, which is generally twice what it costs the creator to make the item. Since different classes get access to certain spells at different levels, the prices for two characters to make the same item might actually be different.
How to calculate the cost of a continuous item?
If a continuous item has an effect based on a spell with a duration measured in rounds, multiply the cost by 4. If the duration of the spell is 1 minute/level, multiply the cost by 2, and if the duration is 10 minutes/level, multiply the cost by 1.5. If the spell has a 24-hour duration or greater, divide the cost in half.
