Throughout the following equations each letter stands consistently for either a non-zero digit or for one of the arithmetic symbols ×, ÷, + and –, with different letters being used for different symbols/digits.
When you have substituted the digits and symbols both equations make sense working from left to right (so that, for example, 5 – 2 × 23 = ((5 – 2) × 23) = 69), are correct, and, as our title implies, a + features somewhere.
AN = ENIGMA
ADDIT = UP
Find the value of AND.
