The following are identities involving spelled out numbers, each of which is encrypted in terms of a simple substitution cipher. Each of these numbers is less than one hundred.

For example, when decrypted: one + two = three and, (two)*(three) - one = five are valid identities. However, words like double, triple, unit, unity, dozen are not allowed.

Decrypt the following to formulate each of these identities:

1. (yes)*(with) = (early)*(wave)
2. (ore)* (ratio) = (per)*(ration)
3. (faced)*(ego) = (most)*(elated)
4. paper – end = (table)*(cam)
5. (cock)*(for) - this = total
6. (fever)*(fly) – not = sting
7. (for)*(some) = new + stand
