1×10

1×10 denotes the product of one and ten. In standard arithmetic, the result is 10. This simple expression illustrates the multiplicative identity: multiplying by 1 leaves the other factor unchanged, so 1×a = a for any number a; here a is 10.

The expression uses the multiplication sign, often written as × or sometimes as a dot in mathematics. The commutative property of multiplication means 1×10 = 10×1, both equaling 10.

In numeral systems, the symbol 10 represents the base value of the system. In base-10 (the decimal system), 10 is the two-digit number ten. In any base b, the numeral "10" stands for the value b, and 1×10 in that base equals the value b, represented as the numeral 10 in that base.

Applications include scaling and units, for example expressing ten units as 1×10 units, or teaching the concept of place value and the identity property in elementary arithmetic.
