If you mean multiplying 10 by 10 and then by 15 then it takes maybe 1 more step but it is very is simple. 10 times 10 is obviously 100 and when dealing with 100 add 2 zero's to the end of your other multiple, which in this case is 15. Your final answer is 1500.
150 Tip: to know ANY sum in the 10 times tables just add a zero to the first number e.g. 7x10=70
150
15
10% times 15%= 10% * 15%= 0.10 * 15%= 1.5% or 0.015
15 x 10 = 150
It is: 15/10 = 1.5
it is: 15 times 10 = 150 square units

10% times 15%= 10% * 15%= 0.10 * 15%= 1.5% or 0.015
10 times 10 is 100, 100 times 15 is 15 with two zeros or 1500.
If you mean (15 -10) times (7 -40) then it is -165
It is: 15/10 = 1.5
15 x 10 = 150
160 ÷ 15 = 10 with remainder 10 (10.6667 times).
It is: 1.3*10^15 = 1,300,000,000,000,000
1350...
10 times
It is: 1.5*10 = 15
it is: 15 times 10 = 150 square units
