Three teachers of Chinese, Mathematics and English in class 6 1 Happy Primary School took a group photo with 46 students in the class. The price in 25 yuan includes 4 photos and a printed 2.8 yuan and a *** 137 yuan.

Calculate the formula according to the meaning of the question:

(46-4)x2.8+25

=40x2.8+25

= 1 12+25

= 137

So a *** 137 yuan.

Mixed operation:

If the first-level operation and the second-level operation exist at the same time, the second-level operation is calculated first. If there are one, two and three operations at the same time (i.e. power, root and logarithm operations), the third operation is calculated first, and then the other two levels are calculated.

If there are brackets, count the numbers in brackets first (no matter what level, count first) The third level should be counted in brackets, and then the second and first levels should be counted.
