Step-by-step explanation:
1. 5 divided 4 times of a number n.
2. 3 subtracted by a number B gives 13.
3. 39 added by a number m divided by 7. (not sure)
4. m divided by 90 gives 15.
5. 32 subtracted by two times of a number N.
31 - as the difference (starting from 1) increases by 1
so:
3,+1=4,+2=6,+3=9,+4=13,+5=18,+6=24,+7=31,
Let a = any number
So, 1 times a = a.
In other words, any number times 1 = any number.
Two samples:
1. 45 x 1 = 45
2. -567 x 1 = -567
