You can figure this out by using mental math if you are a math wizard or you could do it on paper by lining up the decimal points and addind like you would normally. A calculator is also a good option.
418 + 523 + 12 = 953.
9 + 26 + 61 + 8 + 18 + 44 + 10 + 90 = 266
15x26=390
12+14=26+10=36+24=60+10=70+8=78 the answer is 78
It depends where you want the parentheses: 15 + (26 x 10) = 275 (15 + 26) x 10 = 410
The factors of 953 are: 1 and 953 (953 is a prime number).
-16+(-10) = -26
300/1906 = 150/953
26 + 26 + 26 + 26 = 4 x 26 = 104
310 + 26 = 336 3/10 + 2/6 = 9/30 + 10/30 = 19/30
