(2x3)+(3x5)-(3x2)=
2x3=6
3x5=15
3x2=6
So.....
6x25-6=
6x25=150
150+6=156

5x3=15 is the inverse
Commutivity of multiplication or the commutative property of multiplication.
15/40 = (3x5)/(8x5) = 3/8
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
3x5+4=19
2+3*5 = 2 + 15 = 17
6 is 2x3 and 15 is 3x5 just basic facts no exponents
3 x 7 = 3 x (5 + 2) And since multiplication is distributive over addition, 3 x (5 + 2) = 3 x 5 + 3 x 2

3x5
This doesn't make any math sense:2⁴ - 1 + 21 = 14 = 7 +3 x 5
Answer its 0.118
Factor 90 and find a combination that would add up to 21. 3x3x5x2. Try 3x3 plus 5x2. Nope. Try 3x5 plus 3x2. 15 + 6 = 21. Got it!
3x1=3 3x2=6 3x3=9 3x4=12 3x5=15 3x6=18
5x3=15 is the inverse
